(Lull) the children to sleep, and put out the lamp, and serve the guest with what you have with you. It was on this occasion that this verse was revealed:" Those who prefer the needy to their own selves in spite of the fact that they are themselves in pressing need" (Lix. 9).
Sahih Muslim Book 36, Hadith 234
← Previous Hadith I am hard pressed by hunger. He sent (message) to one of his wives (to procure food for him). but she said: By Him Who has sent you with Truth, thrre is nothing with me (to serve him) but only water. He (the Holy Prophet) then sent the (same) message to another, and she gave the same reply, until all of them gave the same reply: By Him Who has sent thee with the Truth, there is nothing with me but only water, whereupon he (the Holy Prophet) said: Allah would show mercy to him who will entertain this guest tonight. A person from the Ansar stood up and said: Messenger of Allah, I (am ready to entertain). He took him to his house and said to his wife: Is there anything with you (to serve the gdest)? She said: No, but only a subsistence for our children. He said: Distract their attention with something, and when the guest enters extinguish the lamp and give him the impression that we are eating. So they sat down. and the guest had his meal. When it was morning he went to Allah's Apostle (ﷺ) who said: Allah was well pleased with what you both did for your guest this night.

Sahih Muslim Book 36, Hadith 233 Next Hadith → Abu Huraira reported that a man came to Allah's Messenger (ﷺ) so that he should entertain him as a guest, but he had nothing with which he could entertain him. He, therefore, asked if there was any person who would entertain him (assuring the audience) that Allah would show mercy to him. A person from the Ansar who was called Abu Talha stood up and he took him to his house. The rest of the hadith is the same and mention is (also) made in that about the revelation of the verse as narrated by Waki'.
