Abu Bakr
There is a dispute over his name being Abdullah. 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. She said Abdullah. I said people are saying Ateeq. She said Abu Quhafa had three children, one was Ateeq, second Mu’taq and third, Otaiq. All three names are similar and derived from the same root."
