There is no blame upon the blind, nor any blame upon the lame, nor any blame upon the sick, nor upon yourselves if you eat from your own houses, or your fathers’ houses, or your mothers’ houses, or your brothers’ houses, or your sisters’ houses, or the houses of your paternal uncles, or the houses of your paternal aunts, or the houses of your maternal uncles, or the houses of your maternal aunts, or those whose keys are in your possession, or those of your friends. There will be no blame on you whether you eat together or separately. So when you enter houses, greet yourselves1 with a salutation from Allah, blessed and good. Thus does Allah clarify His signs for you so that you may apply reason.
