O Believers! enter not into the houses of the Prophet, save by his leave, for a meal, without waiting his time. When ye are invited then enter, and when ye have eaten then disperse at once. And engage not in familiar talk, for this would cause the Prophet trouble, and he would be ashamed to bid you go; but God is not ashamed to say the truth. And when ye would ask any gift of his wives, ask it from behind a veil. Purer will this be for your hearts and for their hearts. And ye must not trouble the Apostle of God, nor marry his wives, after him, for ever. This would be a grave offence with God.
