And this is a Book We have revealed, blessed, verifying that which is before it, and that you may warn the metropolis and those around her; and those who believe in the hereafter believe in it, and they attend to their prayers constantly.

There is no blame on the blind man, nor is there blame on the lame, nor is there blame on the sick, nor on yourselves that you eat from your houses, or your fathers' houses or your mothers' houses, or your brothers' houses, or your sisters' houses, or your paternal uncles' houses, or your paternal aunts' houses, or your maternal uncles' houses, or your maternal aunts' houses, or what you possess the keys of, or your friends' (houses). It is no sin in you that you eat together or separately. So when you enter houses, greet your people with a salutation from Allah, blessed (and) goodly; thus does Allah make clear to you the communications that you may understand.
