Narrated Ibn Abbas: Abu Hurairah narrated that a man came to the Messenger of Allah صلی اللہ علیہ وسلم and said: I had a dream last night, and he then mentioned it. So Abu Bakr interpreted it. The Prophet صلی اللہ علیہ وسلم said: You are partly right and partly wrong.

The tradition mentioned above has also been transmitted by Ibn Abbas through a different chain of narrators. In this version there is no mention of the word qasam (oath). It has the words: "He did not inform him. "

Narrated Abdur-Rahman bin Abi Bakr: Some guests visited us, and Abu Bakr was conversing with the Messenger of Allah صلی اللہ علیہ وسلم at night. He (Abu Bakr) said: I will not return to you until you are free from their entertainment and serving them food. So he brought them food, but they said: We shall not eat it until Abu Bakr comes (back). Abu Bakr then came and asked: What did your guest do? Are you free from their entertainment ? They said: No. I said: I brought them food, but they refused and said: We swear by Allah, we shall not take it until he comes. They said: He spoke the truth. He brought it to us, but we refused (to take it) until you come. He asked: What did prevent you ? He said: I swear by Allah, I shall not take food tonight. They said: And we also swear by Allah that we shall not take food until you take it. He said: I never saw an evil like the one tonight. He said: Bring your food near (you). He (Abdur-Rahman) said: Their food was then brought near them. He said: In the name of Allah, and he took the food, and they also took it. I then informed him that the dawn had broken. So he went to th Prophet صلی اللہ علیہ وسلم and informed him of what he and they had done. He said: You are the most obedient and most trustful of them.

A similar tradition has also been transmitted by Abdur-Rahman bin Abi Bakr through a different chain of narrators. This version adds on the authority of Salim: "Expiation (for breaking the oath) has not reached me. "
