Compilation of the Holy Quran

Since the Holy Quran was not revealed all at once and its
different verses were revealed as and when appropriate,
so it was neither possible nor practicable from the very
beginning to write and preserve it in a book form.
Before one can begin to understand the manner in which
it was preserved, the amazing memories of
the Arab nation must be kept in mind. And of course, the
fact that Allah Himself has said:
“Verily, it is We Who have sent down this Message and it is We Who
shall guard it.” (Surah Hijr; 15:9)

How the Quran was preserved in the time of the Holy Prophet?

 The Quran was revealed to the Holy Prophet through Jibril , who would make
sure that he s learnt its verses by heart.
 Once the Holy Prophet had memorized the verses, Jibril would tell him that
these verses should be placed in so and so Surah in so and so order.
 When the Holy Prophet had learnt the verses, he would then teach them to his
companions who would
 Learn them by heart (these Huffaz were 1000s)
 The scribes of the Holy Prophet, would write the verses under his instruction
on paper, stone tablets, bones, palm leaves, wooden boards or animal skins.
(These companions were about 34).
 Quran was preserved in partial volumes in writing, but primarily in the hearts
of tens of thousands of his companions.

Preservation and Compilation duringthe caliphates of Abu Bakr and Umar

 A large number of Huffaz killed at Yamamah
 Umar proposed to Abu Bakr: Lets Write it down in a single
 After some initial hesitation, he Agreed
 A team of Muqri Sahaba led by Zaid bin Thabit were formed to
conduct this task

How did Zayd ensure authenticity?

 The contributor must have in writing as well as be a Hafiz
 He tested its reliability against his own memory and that of
his team of Huffaz
 Two trustworthy witnesses had testified to the fact that the
particular verse had been written in the presence of the
 The written verses were matched with the collections of
The Final Volume
 This Task was completed by Umar’s time and stayed with him
until his martyrdom.
 Then it went in the custody of Hafsah and thus became
known as Mus’haf-i-Hafsah.

Preservation and Compilation in  the period of Uthman bin 'Affan  Islamic Empire had spread far and wide—

 New people with new tongues, languages, dialects and
pronunciations had become Muslims
 They began to use these to recite Quran in sometimes odd
 Hudhayfa bin Yaman approached the caliph Uthman and told
him about the possible dangers of this
 Uthman immediately took action
 Reassembled a team under Zaid bin Thabit
 Made seven copies of Mushaf e Hafsa
 Sent these to the provincial capitals
 Destroyed any deviant/incomplete manuscript

The 12 Imams

In the Shi’te sect of Islam  known as the Ithna-‘ashariyyah  or Twelvers, the articles of
faith or  fundamentals of Islam differ from those of the Ahle Sunnat or Sunnis.  These
are also known as Usool -ad-Deen or ‘Roots of Religion’. They are
1.  Tawheed: The Oneness of God
2.  'Adl: Belief that God is Just  and He will reward or punish any person according
to his deeds.
3.  Nubuwwat: Belief in the Messengers.
4.   Imamat: Belief in the divinely appointed leadership or the Imams
5.  Qiyaamat: Belief in the Day of Judgment.
Amongst the above, we shall study  Imamate or belief in the Twelve  Imams.
The Twelve    Imams are the spiritual and political successors to  the  Prophet. Each of
them  is an infallible human individual who not only rules over the community with
justice, but  also is able to keep and interpret the Divine Law and its esoteric
meaning. The Prophet and    Imams' words and deeds are a guide and model for the
community to follow; as a result, they must be free from error and sin, and must be
chosen by divine decree, or nass, through the Prophet. It is believed by Twelver Shi'a
Muslims that the Twelve    Imams were foretold in the Hadith of the Twelve
Successors. He is reported to have said:
"The (Islamic) religion will continue until the Hour (day of resurrection), having
twelve Caliphs for you, all of them will be from Quraysh."
The   Imams were  bestowed with  Divine wisdom  (aql) and  knowledge  (hikmah). They
suffered for the sake of religion and  their sufferings were a means of divine grace to
their devotees. Although the    Imam  was not the recipient of a divine revelation, he
had a close relationship with God, through which God guides him, and the    Imam  in
turn guides the people.
There is always an    Imam  of the Age, who is the divinely appointed authority on all
matters of faith and law in the Muslim community.  Hazrat ‘AlÄ« was the first    Imam  of
this lineage, and in the Twelvers' view, the rightful successor to the  Holy  Prophet of
Islam, followed by male descendants of  the Prophet  his daughter Fatimah. Each
Imam  was the son of the preceding      Imam, with the exception of  Hazrat Hussain  ibn
Ali, who was the brother of  Hazrat  Hassan  ibn Ali. The twelfth and final    Imam  is
Hazrat  Muhammad al-Mahdi, who is believed by the Twelvers to be currently alive,
and hidden till he returns to bring justice to the world.
Belief in    Imamat,  the divinely appointed leadership after the death of the Holy
Prophet is an integral part of Shi’te faith.  Their role is  to protect and guide mankind
with the revealed Truth, the Holy Qur'an and the true practices of the Holy Prophet
himself. They play  an integral part in the protection of all the Messengers and their
divine Messages. Allah appointed  them  through the Holy Prophet himself  to protect
mankind from misrepresenting and misinterpreting the Truth. They are sinless
(ma'soom) and perfect in  the highest sense of the word. As the    Imams have direct
knowledge from God, and their verdict is the verdict of God.

Hazrat Imam Ali ibn Abu Talib (23 pre-Hijri to 40 AH)

He was the first    Imam  and is also called Amir al-mu'min or Commander of the
faithful. His father Hazrat Abu Talib was the uncle, guardian and lifelong supporter of
the Holy Prophet.
Hazrat Imam  Ali was born ten years before the commencement of the prophetic
mission of the Prophet. When six years old he was placed directly under the
guardianship and custody of the Holy Prophet who brought him up like his own son.
When the Prophet received the first revelation,  Hazrat Imam Ali was the first person
to publicly declare his faith in the Divine Message.
Hazrat Imam  Ali became the supporter and deputy of the Prophet and was by his
side during the hard times in Makkah. On the night of the migration to Madina
(hijrah) when the infidels had surrounded the house of the Prophet and were
determined to invade the house at the end of the night and  assassinate  him as he
slept, Ali  slept in place of the Prophet, while the Prophet left the house and set out
for Madina. After the departure of the Prophet, Ali gave back to the people the trusts
and charges that they had deposited  with the Prophet. Then he went to  Madinah
with his mother, the daughter of the Prophet, and two other women.
At Madina when the Prophet was creating bonds of brotherhood among his
companions he selected Ali as his brother. The Prophet gave Fatimah, his beloved
daughter to Ali as his wife.
Ali participated bravely in the battles of  the Holy Prophet, except the battle of Tabuk
when he was ordered to stay in Madina in place of the Holy Prophet.
Ali was thirty-three years old when the Prophet died. He spent the next twenty five
years as an advisor to the first three  caliphs and in educating people in Islamic
He became the fourth Caliph in 35 A.H.  His caliphate of lasted for nearly five years,
throughout which he followed the way of the Prophet and gave his caliphate the
form of a spiritual movement and renewal.
Unfortunately, his caliphate was ridden with civil strife. The  Muslims  had split into
two  groups, one supporting him and the other supporting A'ishah and Muawiya.
These two armies fought  the "Battle of the Camel,"  and then the  "Battle of Siffin."
After this a faction of his own supporters turned traitor. They are known as the
Khawarij.  He also fought against the Khawarij in  the  Battle of Nahrawan Therefore,
most of the days of Ali's caliphate were spent in overcoming internal opposition.
Finally, in the morning of the 19th of Ramadan in the year 40 A.H., while praying in
the mosque of Kufa, he was wounded by one of the Khawarij and died as a martyr
during the night of the 21st of Ramadan. He was buried in Najaf, Iraq.
Ali had no shortcomings from the point of view of human perfection. And in the
Islamic virtues he was a perfect example of the  upbringing and training given by the
Prophet. He was equally learned in  science  and wisdom and was  most eloquent. His
courage was proverbial and services to Islam were exemplary.

Hazrat Imam Hassan ibn Ali (3-50 AH)

He was the second  Imam and was also called al-Mujtaba. He and his brother    Imam
Hussain were the two sons of Amir al-mu'minin Ali and Fatimah, the daughter of the
Holy  Prophet. Many times the  Holy  Prophet had said, "Hassan  and  Hussain  are my
children." Because of these same words        Imam  Ali would say to his other children,
"You are my children and Hassan and Hussain are the children of the Prophet."
Hazrat Imam Hassan was born in the year 3 A.H. in Madinah and shared in the life of
the Prophet for somewhat over seven years, growing up during that time under his
loving care. Soon after the death of the Prophet,  Hazrat  Fatimah also died and
Hassan was placed directly under the care of his noble father.
After the death of his father, through Divine Command and according to the will of
his father,      Hazrat Imam  Hassan  became  Imam; he also occupied the function of
caliph for about six months.
The governor of Syria, Mu'awiyah, who had been an opponent of his  father as well,
challenged the caliphate of   Hazrat Imam  Hassan. War ensued, and finally the  Hazrat
Imam  made peace  and  yielded  to  the caliphate to Mu'awiyah, under certain
conditions. He did this as he desired to put an end to the civil strife and bloodshed
amongst the Muslims.
Hazrat  Imam  Hassan  devoted the rest of his life to  teaching and training scholars in
the Islamic faith, undergoing extreme hardship and persecution by his political rivals.
Finally, in  the year 50 A.H.  allegedly motivated by the Caliph Mu'awiyah, his wife
poisoned him and he was martyred.
In human perfection,  Hazrat  Imam  Hassan  was reminiscent of his father and a
perfect example of his noble grandfather.  There are many traditions of the Holy
Prophet and Ali concerning the fact that  Hazrat  Imam  Hassan  would  be the  Imam
after his noble father.

Hazrat Imam Hussain bin Ali (4-61 AH)

Hazrat  Imam  Hussain,  known as ‘Sayyid al-Shuhada' or  "the chief of  martyrs"), was
the second child of Ali and Fatimah. He  was born in the year 4 A.H. and after the
martyrdom of his brother,  Hazrat  Imam  Hassan Mujtaba, became  Imam  through
Divine Command and his brother's will.
Hazrat  Imam  Hussain was Imam  for a period of ten years. The last six months of his
Imamate  coincided  with the caliphate of Mu'awiyah.    Hazrat  Imam  Hussain lived
under the most difficult outward conditions of suppression and persecution. This was
due to the fact that, first of all, religious laws and regulations had lost much of their
weight and credit,  and the edicts of the Umayyad government had gained complete
authority and power. Secondly, Mu'awiyah and his aides made use of every possible
means to put aside and move out of the way the Household of the Prophet and the
Shi'ah, and thus obliterate the name of Hazrat Imam Ali and his family. And above all,
Mu'awiyah wanted to strengthen the basis of the caliphate of his son, Yazid, who
because of his lack of principles and scruples was opposed by a large group of
Muslims. Therefore, in order to quell all  opposition, Mu'awiyah had undertaken
newer and more severe measures. By force and necessity,   Hazrat Imam  Hussain had
to endure these days and  he had to suffer  every kind of mental and spiritual agony
and affliction from Mu'awiyah and his aides, until in  the middle of the year 60 A.H.
Mu'awiyah died and his son Yazid took his place.
Yazid, immediately after the death of his father ordered the governor of  Madinah
either to force a pledge of allegiance from   Hazrat  Imam  Hussain or send his head to
After the governor of  Madinah  informed    Hazrat  Imam  Hussain of this demand, the
Hazrat Imam, in order to think over the question, asked for a delay and overnight
started with his family toward Makkah. He sought refuge in the sanctuary of God
which in Islam is the official place of refuge and security. This event occurred toward
the end of the month of Rajab and the beginning of Sha'ban of 60 A.H. For nearly
four months    Hazrat  Imam  Hussain stayed in Makkah in refuge. This news spread
throughout the Islamic world. On the one hand many people who were tired of the
iniquities of Mu'awiyah's rule and were even more dissatisfied when Yazid became
caliph, corresponded with  Hazrat  Imam  Hussain and expressed their sympathy for
him. On the other hand a flood of letters began to flow, especially from Iraq and
particularly the city of Kufa, inviting the Imam to go to Iraq and accept the leadership
of the populace there with the aim of beginning an uprising to overcome injustice
and iniquity. Naturally such a situation was dangerous for Yazid.
The stay of  Hazrat  Imam  Hussain in Makkah continued until the season for
pilgrimage when Muslims from all over the world poured in groups into Makkah in
order to perform the rites of the  Hajj. The Hazrat Imam  discovered that some of the
followers of Yazid had entered Makkah as pilgrims (hajjis) with the mission to kill the
Imam  during the rites of  Hajj with the arms they carried under their special
pilgrimage dress (ihram). The  Imam  shortened the pilgrimage rites and decided to
leave. Amidst the vast crowd of people he stood up and in a short speech announced
that he was setting out for Iraq. In this short speech he also declared that he would
be martyred and asked Muslims to help him in attaining the goal he had in view and
to offer their lives in the path of God. The next day he set out with his family and a
group of his companions for Iraq.
Hazrat  Imam  Hussain was determined not to give his allegiance to Yazid,  knowing
fully  well that he would be killed. He was aware that his death was inevitable in the
face of the awesome military power of the Umayyads, supported as it was by
corruption in certain sectors, spiritual decline, and lack of will power among the
people, especially in Iraq. Some of the outstanding people of Makkah stood in the
way of    Hazrat  Imam  Hussain and warned him of the danger of the move he was
making. But he answered that he would never pay allegiance to a ruler like Yazid and
give  his approval to a government of injustice and tyranny. He added that he knew
that wherever he turned or went he would be killed. He would leave Makkah in
order to preserve the respect  of  the house of God and not allow this respect to be
destroyed by having his blood spilled there. While on the way to Kufa and still a few
days' journey away from the city, he received news that the followers of Yazid in
Kufa had put to death the representative of the  Imam in that city and also one of the
Imam's determined supporters who was a well-known man in Kufa.
Approximately seventy kilometers from Kufa, in a desert named Karbala, the  Imam
and his entourage were surrounded by the army of Yazid. For eight days they stayed
in this spot during which the circle narrowed and the number of the enemy's army
increased. Finally the  Imam, with his household and a small number of companions
were encircled by an army of thirty thousand soldiers.
On the tenth day of Muharram of the year 61/680 the  Imam  lined up before the
enemy with  his small band of followers, less than ninety persons consisting of forty
of his companions, thirty some members of the army of the enemy that joined him
during the night and day of war, and his Hashimite family of children, brothers,
nephews, nieces and  cousins. That day they fought from morning until their final
breath, the Imam, the young Hashimites and the companions were all martyred.
The army of the enemy, after ending the war, plundered the haram of the Imam  and
burned his tents. They decapitated the bodies of the martyrs, denuded them and
threw them to the ground without burial. Then they moved the  remaining  members
of the  family, all of whom were helpless women and girls, along with the heads of
the martyrs, to Kufa. Among the prisoners there were  three male members: a
twenty-two year old son of  Imam  Hussain who was very ill and unable to move,
namely  Hazrat  Ali ibn Hussain, the fourth  Imam; his four year old son,  Hazrat
Muhammad ibn Ali, who became the fifth Imam.
The event of Karbala was a colossal crime that reminds us how the third Imam down
his life for the sake of Islam but refused to comprise on principles.

Hazrat Imam Ali ibn Husayn (38-95 AH)

He was known as al-Zayn al-'Abedin  or the Crown amongst the worshippers.    Hazrat
Imam  Ali was  the only son of  Hazrat Imam  Husayn to survive, for his other three
brothers  Hazrat Ali Akbar, aged twenty-five, five year old  Hazrat Ja'far and  Hazrat Ali
Asghar (or 'Abdallah) who was a suckling baby were martyred during the event of
The  Imam  had also accompanied his father on the journey that terminated fatally in
Karbala, but because of severe illness and the inability to carry arms or participate in
fighting he was prevented from taking part in the holy war and being martyred. So
he was sent with the womenfolk to Damascus. After spending a period in
imprisonment he was sent with honour to  Madinah  because Yazid wanted to
conciliate public opinion. But for a second time, by the order of the Umayyad caliph,
'Abd al-Malik, he was chained and sent from  Madinah  to Damascus and then again
returned to Madinah.
The fourth Imam, upon returning to  Madinah, retired from public life completely,
closed the door of his house to strangers and spent his time in worship. He was in
contact only with  those  seeking knowledge from him and other scholarly activities.
Among the works of the fourth Imam  is a book called Sahifa al-Sajjadiyah. It consists
of fifty-seven prayers concerning the most sublime Divine sciences and is known as
"The Psalm of the Household of the Prophet."
The fourth Imam  was  poisoned by Walid ibn 'Abd al-Malik through the instigation of
the Umayyad caliph Hisham after thirty-five years of Imamate.

Hazrat Imam Muhammad ibn Ali (57 – 114 AH)

The Fifth  Imam  was given the title Baqir, meaning he who cuts and dissects. He was
just four years old at Karbala and thus escaped being murdered. After his father,
through Divine Command and the decree of those who went before him, he became
During the  Imamate of the fifth  Imam, due to revolts against the Umayyads, he and
his family were left alone somewhat and thus were able to pursue scholarly activities
Large numbers of people would come to  Hazrat Imam  Muhammad for spiritual and
academic guidance.
In the year 114  AH  he  was martyred through poisoning by  the nephew of Hisham,
the Umayyad caliph.

Hazrat Imam Ja'far ibn Muhammad (83 – 148 AH)

The Sixth  Imam  was known as As-Sadiq, or the Truthful One. He was the son of the
fifth  Imam  and after the death of his father, became  Imam  by Divine Command and
decree of those who came before him.
During the  Imamate of the sixth  Imam  greater possibilities and a more favourable
climate existed to propagate religious teachings. This came about as a result of
revolts against the Umayyads.  For twenty years, he had a free hand for the
propagation of the true teachings of Islam and the sciences of the Household of the
He instructed many scholars in different fields of the intellectual and transmitted
sciences, such as Mu'min Taqi, Jabir ibn Hayyan, Sufyan Thawri and Abu Hanifah. It is
said that his classes and sessions of instruction produced four thousand scholars of
hadith and other sciences. The number of traditions preserved from the fifth and
sixth    Imams is more than all the  hadith that have been recorded from the Prophet
(sawas) and the other ten  Imams combined.
The  Imam  was arrested  several times by both Umayyad and  Abbasid caliphs, and
finally when he was released he spent the rest of his life in hiding in Madinah.
He too  was  poisoned and martyred through the intrigue of  the Abbasid Caliph

Hazrat Imam Musa ibn Ja'far (128-183 AH)

The Seventh Imam, also known as Kazim, became Imam after the death of his father,
through Divine Command and the decree of his forefathers.
The seventh Imam  was a contemporary of the Abbasid caliphs, Mansur, Hadi, Mahdi
and Harun. He lived in very difficult times and in hiding, until finally Harun went  for
Hajj. In  Madinah, he had the  Imam  arrested while praying in the Mosque of the
Prophet. He was chained and imprisoned, then taken from  Madinah  to Basra and
from Basra to Baghdad where for years he was transferred from one prison to
another. Finally he died in Baghdad in the Sindi ibn Shahak prison through poisoning
and was buried in the cemetery of the Quraysh which is now located in the city of

Hazrat Imam Ali ibn Musa (148-203 AH)

The Eight Imam was given the title of al-Ridha and was the son of the seventh Imam.
He was active in the scientific and scholarly debates that were popular at that time.
He followed the scholarly tradition as was befitting an Imam.
The period of his  Imamate coincided with Mamun  Abbasi.  Mamun, in order to end
the conflict between the ruling class and the family of the Prophet,  offered him  the
caliphate and then the succession to the caliphate. The  Imam, after much hesitation
and conditions, accepted the successorship.
But then Mamun had second thoughts and  had the  Imam  poisoned and martyred.
The Imam was buried in the city of Tus in Iran, which is now called Mashhad.
Hazrat Imam Muhammad ibn Ali (196-220 AH)
The Ninth Imam  was called  Taqi  and was  the son of the eighth. He was born in
At the time of the death of his father he was in  Madinah. Ma'mun called him to
Baghdad which was then the capital of the caliphate and outwardly showed him
much kindness. He even gave the    Imam  his daughter in marriage and kept him in
Baghdad. In reality he wanted to keep a close watch upon the    Imam  through his
daughter. The    Imam  spent some time in Baghdad and then with the consent of
Ma'mum set out for Madinah where he remained until Ma'mun's death.
In 220 AH, he was poisoned by his wife, the daughter of Ma'mun, at the instigation
of the Abbasid caliph Mu'tasim. He was buried next to his grandfather, the seventh
Imam, in Kazimayn

Hazrat Imam Ali ibn Muhammad Naqi (212-254 AH)

The Tenth  Imam  is also called  Naqi and Hadi. He was the son of the ninth  Imam.  At
that time    Ali ibn Muhammad Naqi was in  Madinah. There he became the    Imam
through Divine Command and the decree of the    Imams before him. He stayed in
Madinah teaching religious sciences until the time of Mutawakkil, who was an ardent
but secret hater of the  Imam and his family.
In 243  AH,  Mutawakkil  deceptively arranged  for the    Imam  to come to visit him in
Samarrah, just to humiliate him. Throughout his caliphate, Mutawakkil spared no
chance to insult and harm the  Imam and the members of the Prophet’s family.
In 254 AH, the tenth    Imam  too was  poisoned and martyred  by Mu'tazz the Abbasid

Hazrat Imam Hasan ibn Ali (232-260 AH)

The Eleventh  Imam, also known as Hassan Al-Askari was the son of the tenth  Imam,
and  gained the    Imamate after the death of his noble father, through Divine
Command and through the decree of the previous  Imams.
During the seven years of his    Imamate, due to untold restrictions placed upon him
by the caliphate, he lived in hiding and dissimulation (taqiyah). He did not have any
social contact with even the common people among the Shi'ite population. Only the
elite of the Shi'ah were able to see him. Even so, he spent most of his time in prison.
The caliph of the time had decided definitely to put an end to  the    Imamate in The
Followers of Ahlu Bayt through every possible means and to close the door to the
Imamate once and for all.
However, he still managed to train many scholars and intellectuals in his lifetime.
He was poisoned and martyred through instigation of the Abbasid caliph Mu'tamid.

Hazrat Imam Muhammad ibn Hasan (256 AH-  )

The Twelfth    Imam  is the  promised Mahdi, who is usually mentioned by his title of
Imam-i 'Asr (the    Imam  of the "Period") and Sahib al-Zaman (the Lord of the Age),
and is the son of the eleventh  Imam.
He was born in Samarrah and until his father’s  martyrdom, lived under his care and
tutelage. He was hidden from public view and only a few of the elite among the
Shi'ah  were able to meet him. After the martyrdom of his father he became    Imam
and by Divine Command went into occultation (ghaybat). Thereafter he appeared
only to his deputies and even then only in exceptional circumstances.  Through these
special deputies he would answer the demands and questions of the Shi'ah.
But in 329 AH, he went into come occultation which will continue as long as God wills
it. However, he shall eventually return as per the prophecy of the Prophet to lead his
followers once again.
In the  meantime, it  is he who directs man's spiritual life and orients the inner aspect
of human action toward God: Clearly, his physical presence or absence has no effect
in this matter. The    Imam  watches over Shi’a  inwardly and is in communion with the
soul and spirit of men even if he be hidden from their physical eyes. His existence is
always necessary even if the time has not as yet arrived for his outward appearance
and the universal reconstruction that he is to bring about.
The reappearance  of the twelfth  Imam  is awaited by the Shi’ah and when he shall
return (as contained in many ahadith), he shall perform many great tasks and rid the
world of evil.
