O Believers! Do not enter the houses of the Holy Prophet [blessings and peace be upon him] unless permission is granted to you for a meal. Nor (reach so early as to) wait for the cooking of the meal. But when you are invited then enter (at that time). Then when you have eaten the meal, (get up from there and) disperse without delay and do not linger on in eagerness for talk. Surely your (sitting for long in this) manner discomforts the Holy Prophet[blessings and peace be upon him]; and he feels reluctant to (ask) you (to leave) but Allah does not hesitate in (saying) the Truth. And when you ask them (the pure wives) for something, ask them from behind a curtain. This (regard and nice manner) causes great purity for your hearts and for their hearts. And it is not (at all lawful) for you that you cause inconvenience to the Holy Messenger of Allah [blessings and peace be upon him], nor is this (lawful) that you marry his (pure) wives after him, till the end of time. Surely it is the most grievous sin in the sight of Allah.
