There is no blame upon the blind, nor blame upon the lame, nor blame upon the sick nor on yourselves if 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 those whereof you possess the keys, or of your friend. There is no crime upon you that you eat all together or separately. But when you enter houses, then greet each other with a salutation from Allah, blessed and pure. Thus does Allah explain to you His revelations in order that you may understand.
