And who is more unjust than he who prevents (men) from the masjids of Allah, that His name should be remembered in them, and strives to ruin them? (As for) these, it was not proper for them that they should have entered them except in fear; they shall meet with disgrace in this world, and they shall have great chastisement in the hereafter.

O you who believe! do not enter the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished-- but when you are invited, enter, and when you have taken the food, then disperse-- not seeking to listen to talk; surely this gives the Prophet trouble, but he forbears from you, and Allah does not forbear from the truth And when you ask of them any goods, ask of them from behind a curtain; this is purer for your hearts and (for) their hearts; and it does not behove you that you should give trouble to the Messenger of Allah, nor that you should marry his wives after him ever; surely this is grievous in the sight of Allah.

That He may cause the believing men and the believing women to enter gardens beneath which rivers flow to abide therein and remove from them their evil; and that is a grand achievement with Allah
