There is no hindrance to the blind, and no hindrance to the lame, and no hindrance to the sick, and none upon yourselves that you eat from your houses, or the houses of your fathers, 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 what ye possess the keys of, or of your friend, there is no crime on you that ye eat all together or separately. And when ye enter houses then greet each other with a salutation from God, blessed and good. Thus does God explain to you His signs, haply ye may understand.
