Musnad Ahmad 1713

Abu "Uthman narrated that "Abdur -Rahman bin Abi Bakr told him that Ashabus-Suffah were poor people. The Messenger of Allah (ﷺ) said: "Whoever has food for two, let him take a third person with him; whoever has food for four, let him take a fifth and sixth person with him,” or words to that effect. Abu Bakr brought three People with him and the Prophet of Allah (ﷺ) took ten people with him. He said: That was me and my father and my mother- and I do not know if he said: - and my wife and a servant whom we shared with the household of Abu Bakr (رضي الله عنه).
