Abdullah and Muhammad narrated from their father Abu Bakr (bin Muhammad bin Amr bin Hazm) in the same manner (as mentioned above), except that one of them said: The boy was thirteen years old, and the other said: (the will was made) before reaching puberty. Imam Darimi, may Allah have mercy on him, said: «عن ابنيه» This refers to the two sons of Abu Bakr (Abdullah and Muhammad).
