Sayyiduna Anas bin Malik (may Allah be pleased with him) says regarding this verse (the command of Allah Almighty): "Do not enter the houses of the Prophet until permission is given to you for a meal." Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) had food prepared after marrying one of his noble wives (for the wedding feast). He sent me, and I brought some people. They ate the food, then the Prophet Muhammad (peace and blessings be upon him) stood up and went outside. He came to the house of Sayyidah Aisha (may Allah be pleased with her), and I also followed him. The Prophet Muhammad (peace and blessings be upon him) entered the house and found two men inside. When he saw them, he turned back and did not speak to them. Both of them got up and left the house. On this occasion, the verse regarding the command of hijab was revealed: "O you who believe! Do not enter the houses of the Prophet until permission is given to you for food, and you are not looking towards the utensils."
