Much of the available knowledge about Muhammad comes through Abu Bakr's daughter, Aisha. Imam Muhammad al Baqir, the father of Imam Jafar Sadiq, also called Abu Bakr with the title Siddiq. Jafar al-Sadiq was also the successor of the Naqshbandi Sufi order believed to be originating from Abu Bakr himself. Jafar was a direct descendant of Abu Bakr from his maternal side, as well as being a descendant of Ali from his father's side. Imam Jafar al Sadiq famously narrated how the title Siddiq was given to Abu Bakr from Muhammad. He was mentioned in the Quran as the "second of the two who lay in the cave" in reference to the event of hijra, where with Muhammad he hid in the cave in Jabal Thawr from the Meccan search party that was sent after them, thus being one of few who were given direct mention in the Quran. All three names are similar and derived from the same root." She said Abu Quhafa had three children, one was Ateeq, second Mu’taq and third, Otaiq. Ibn Hajar in Al-Isaabah, and many other narrations, narrates from Qasim Ibn Muhammad Ibn Abi Bakr, "I asked Ayesha the name of Abu Bakr. There is a dispute over his name being Abdullah. He was called Al-Siddiq (the truthful) by Muhammad after he believed him in the event of Isra and Mi'raj when other people didn't, and Ali confirmed that title several times. Muhammad later reaffirmed this title when he said that Abu Bakr is the "atiqe" (the one saved from hell fire by God). One of his early titles, preceding his conversion to Islam, was atiqe, "the saved one".

In Arabic, the name Abd Allah means "slave of Allah".
