Anas bin Malik (RA) reported: Allah's Messenger ( صلی اللہ علیہ وسلم ) contracted marriage and he went to his wife. My mother Umm Sulaim prepared hais and placed it in an earthen vessel and said: Anas, take it to Allah's Messenger ( صلی اللہ علیہ وسلم ) and say: My mother has sent that to you and she offers greetings to you, and says that it is a humble gift for you on our behalf, Messenger of Allah. So I went along with it to Allah's Messenger ( صلی اللہ علیہ وسلم ) and said: My mother offers you salutations, and says that it is a humble gift for you on our behalf. He said: Place it here, and then said: Go and invite on my behalf so and so and anyone whom you meet, and he even named some persons. He (Anas) said: I invited whom he had named and whom I met. I (one of the narrators) said: I said to Anas (RA): How many (persons) were there? He (Anas) said: They were about three hundred persons. Then Allah's Messenger ( صلی اللہ علیہ وسلم ) (said to me): Anas, bring that earthen vessel. They (the guests) then began to enter until the courtyard and the apartment were fully packed. Allah's Messenger ( صلی اللہ علیہ وسلم ) said: Make a circle of ten (guests), and every person should eat from that nearest to him. They began to eat, until they ate to their fill. A group went out (after eating the food), and another group came in until all of them had eaten. He (the Holy Prophet) said to me: Anas, lift it (the earthen vessel), so I lifted it, but I could not assess whether it had more (food) when I placed it (before Allah's Messenger) or when I lifted it (after the people had been served out of it). A group among them (the guests) began to talk in the house of Allah's Messenger ( صلی اللہ علیہ وسلم ) and the Messenger of Allah ( صلی اللہ علیہ وسلم ) was sitting and his wife had been sitting with her face turned towards the wall. It was troublesome for Allah's Messenger ( صلی اللہ علیہ وسلم ) , so Allah's Messenger ( صلی اللہ علیہ وسلم ) went out and greeted his wives. He then returned. When they (the guests) saw that Allah's Messenger ( صلی اللہ علیہ وسلم ) had returned they thought that it (their overstay) was something troublesome for him. He (the narrator) said: They hastened towards the door and all of them went out. And there came Allah's Messenger ( صلی اللہ علیہ وسلم ) and he hung a curtain and went in, and I was sitting in his apartment and he did not stay but for a short while. He then came to me and these verses were revealed. Allah's Messenger ( صلی اللہ علیہ وسلم ) came out and recited them to the people: "O you who believe, enter not the houses of the Prophet ( صلی اللہ علیہ وسلم ) unless permission is given to you for a meal, not waiting for its cooking being finished-but when you are invited, enter, and when you have taken food, disperse not seeking to listen to talk. Surely this gives the Prophet ( صلی اللہ علیہ وسلم ) trouble", to the end of verse (xxxiii. 53). (Al-Ja'd said that Anas [b. Malik] stated: I am the first amongst the people to hear these verses), and henceforth the wives of the Apostle ( صلی اللہ علیہ وسلم ) began to observe seclusion (al-hijab).
