Believers, let [even] those whom you rightfully possess, and those who are under age ask your leave on three occasions when they come in to see you: before the morning prayer, when you have taken off your garments in the heat of noon, and after the evening prayer. These are the three occasions for your privacy. At other times, there is nothing blameworthy if you or they go around visiting one another. Thus God makes clear to you His revelations: God is all knowing and wise. 58 When your children have reached the age of puberty, they should similarly ask your leave (for entering) as others did before them. God thus clearly explains His commands to you, for God is all-knowing and all-wise. 59 There is no sin for such elderly women as are past the age of marriage, if they lay aside their outer graments provided that they do not mean to display their adornment. Nevertheless, if they behave modestly, it would be better for them: for Allah hears everything and knows everything. 60 No blame is there upon the blind nor any blame upon the lame nor any blame upon the sick nor on yourselves if ye 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 fathers' brothers, or the houses of your fathers' sisters, or the houses of your mothers' brothers, or the houses of your mothers' sisters, or (from that) whereof ye hold the keys, or (from the house) of a friend. No sin shall it be for you whether ye eat together or apart. But when ye enter houses, salute one another with a greeting from Allah, blessed and sweet. Thus Allah maketh clear His revelations for you, that haply ye may understand. 61
