There is no bar on (and not improper for) the blind, nor is there any bar on (nor improper for) the lame, nor is any bar on (nor improper for) the sick, nor on your people that you eat from your own houses, or the houses of your fathers (and children) or the houses of your mothers, or the houses of your brothers, or the houses of your sisters, 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 (from) that of which the keys are in your possessions (- which is under your charge), or (from the house of) a friend of yours. No blame lies on you whether you eat together or separately. And when you enter houses greet your people (present therein) with the salutation prescribed by Allâh (a salutation) full of blessings and purity. That is how Allâh explains to you (His) commandments that you may abstain (from evils).
