Abdur-Rahman bin Abi Bakr narrated that:
the people of as-Suffah were poor people and on one occasion the Messenger of Allah (ﷺ) said: "Whoever has enough food for two people, let him take three with him, and whoever has enough food for four people, let him take a fifth or a sixth with him," or words to that effect. Abu Bakr took three people with him and the Prophet of Allah (ﷺ) took ten. Abu Bakr took three and he (the narrator) 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. Abu Bakr ate dinner with the Prophet (ﷺ) , then he stayed until "Isha" prayer was offered, then he went back and stayed until the Messenger of Allah (ﷺ) became drowsy, and he came after as much of the night had passed as Allah willed. His wife said to him: What kept you away from your guests? Or she said: your guest. He said: Have you not given them dinner? She said: They refused (to eat) until you came, They brought the food to them, but they insisted on not eating. I went and hid myself, and he said: O ignorant fellow! And he reprimanded me and berated me. He said: Eat, but you may not enjoy it. And he said: By Allah, I will never eat it. By Allah, we did not take any morsel but there appeared beneath it more of it, until we had eaten our fill and there was more of it than before. Abu Bakr looked at it and saw that it was as it had been before or more than that. He said to his wife: O sister of Banu Firas, what is this? She said: No, O pleasure of my eye, now it is three times more than it was before. Abu Bakr ate some of it and said: That was from the Shaitan - meaning his oath. Then he ate a morsel of it and took it to the Messenger of Allah (ﷺ), and the Messenger of Allah (ﷺ) found it in the morning. He said: There was a treaty between us and some people which came to an end, and we appointed twelve men, each of whom had many men with him, and Allah knows best how many were with each man, and all of them ate from it.
