And hold fast by the covenant of Allah all together and be not disunited, and remember the favor of Allah on you when you were enemies, then He united your hearts so by His favor you became brethren; and you were on the brink of a pit of fire, then He saved you from it, thus does Allah make clear to you His communications that you may follow the right way.

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.
