O you who have faith! Do not enter the Prophet’s houses unless permission is granted you for a meal, without waiting for it to be readied. But enter when you are invited, and disperse when you have taken your meal, without settling down to chat. Indeed such conduct torments the Prophet, and he is ashamed of [asking] you [to leave]; but Allah is not ashamed of [expressing] the truth. And when you ask anything of [his] womenfolk, ask it from them from behind a curtain. That is more chaste for your hearts and their hearts. You may not torment the Apostle of Allah, nor may you ever marry his wives after him. Indeed that would be a grave [matter] with Allah.
