Abu Bakr ( Abdullah ibn Abi Quhafa ) (, c. 573 CE – 23 August 634 CE ) also known as Abū Bakr as-Șiddīq ( Arabic: أبو بكر الصديق ) was a senior companion ( Sahabi ) and the father-in-law of the Islamic prophet Muhammad.

As Caliph, Abu Bakr succeeded to the political and administrative functions previously exercised by Muhammad, since the religious function and authority of prophethood ended with Muhammad's death according to Islam.

As a young man, Abu Bakr became a cloth merchant and he traveled extensively in Arabia and neighboring lands in the Middle East, through which he gained both wealth and experience.

Not long after, Abu Bakr accepted Islam and was the first person outside the family of Muhammad to openly become a Muslim.

Abu Bakr served as a trusted advisor and close friend to Muhammad.

Muhammad later reaffirmed this title when he said that Abu Bakr is the ' atiqe ' ( the one saved from hell fire by God ).

Imam Jafar al Sadiq famously narrated how the title Siddiq was given to Abu Bakr from Muhammad.

He was also a direct descendant of Abu Bakr from his maternal side, as well as being a paternal descendant of Ali from his father's side.

Jafar al-Sadiq was also the successor of the Naqshbandi Sufi order originating from Abu Bakr himself.

Imam Muhammad al Baqir, the father of Imam Jafar Sadiq also called Abu Bakr with the title Siddiq.

Abu Bakr was born in Mecca some time in 573 CE, to a rich family in the Banu Taym clan of the Quraysh tribe.

The lineage of Abu Bakr joined that of Muhammad in the eighth degree in their common ancestor Murrah ibn Ka ' b.

The lineage of Abu Bakr was: Abu Bakr ; the son of Uthman Abu Quhafa ; the son of Amar ; the son of Umru ; the son of Kaab ; the son of Saad ; the son of Taym ; the son of Murrah.

Shia claim that the despair felt by Umar at the time of Muhammad's death was not genuine, they insist that there was no despair, only threats aimed to delay matters so that his friend and confederate Abu Bakr could return before Ali was confirmed as the successor.

With Abu Imran's recommendation, Yahya ibn Ibrahim made his way to the ribat of Waggag ibn Zelu in the Sous valley of southern Morocco, to seek out a Maliki teacher for his people.

Abu Bakr's Caliphate lasted for a little over two years ( or 27 months ), ending with his death after an illness.

In his early years he played with the camel foals and goats, and his love for camels earned him the nickname " Abu Bakr ", the father of the foal of the camel.

Like other children of the rich Meccan merchant families, Abu Bakr was literate and developed a fondness for poetry.

The father of Abu Bakr asked him to for why doesn't he liberate strong and young slaves who could be a source of strength for him, Abu Bakr replied that he was freeing the slaves for the sake of God, and not for his own sake.
