Sahih al-Bukhari 5163

Abu 'Uthman al-Ja'd heard Anas ibn Malik say in the mosque of the Banu Rifa'a: "When the Prophet, may Allah bless him and grant him peace, passed by the area where Umm Sulaym was, he came inside and greeted her." Then he said, "When the Prophet, may Allah bless him and grant him peace, married Zaynab, Umm Sulaym said to me, 'We should give a gift to the Messenger of Allah.' I said to her, 'Do so.' She took some dates, ghee and dried curd and made haysa* in a pot and sent it with me to him. I took it to him and he told me, 'Put it down. Then he ordered me, 'Invite some men for me,' whom he named, 'and invite whomever you meet for me.' I did what he had ordered me. When I returned, the house was full of people. I saw the Prophet, may Allah bless him and grant him peace, place his hands on that haysa and say whatever Allah wished over it. Then he began to invite them in groups of ten to eat from it. He told them, 'Mention the Name of Allah. Each man should ear from what is near him.' When they all had finished, some of them went out and a group remained conversing and I was unhappy about it. Then the Prophet, may Allah bless him and grant him peace, went out towards the rooms (of his wives) and I went out after him and said, 'They have gone.' He returned and entered the room and let the curtain down while I was in the room. He was reciting, 'O you who believe! Do not go into the Prophet's rooms except when you are invited to come and eat. Do not wait there while the food is being cooked. However, when you are called go in and when you have eaten disperse, not remaining there to chat with one another. Doing that causes annoyance to the Prophet though he is too reticent to tell you so. But Allah is not reticent with the truth.' (33:53)." Abu 'Uthman mentioned that Anas said that he served the Messenger of Allah, may Allah bless him and grant him peace, for ten years. [*haysa: a dish in which dates are mixed with ghee and dried curd and kneaded together.]
