Anas bin Malik:
When Allah's Messenger (ﷺ) married Zainab bint Jahsh, he invited the people to a meal. They took the meal
and remained sitting and talking. Then the Prophet (showed them) as if he is ready to get up, yet they
did not get up. When he noticed that (there was no response to his movement), he got up, and the
others too, got up except three persons who kept on sitting. The Prophet (ﷺ) came back in order to enter
his house, but he went away again. Then they left, whereupon I set out and went to the Prophet (ﷺ) to tell
him that they had departed, so he came and entered his house. I wanted to enter along with him, but he
put a screen between me and him. Then Allah revealed:
'O you who believe! Do not enter the houses of the Prophet...' (33.53)
