O believers, let those your right hands own and those of you who have not reached puberty ask leave of you three times -- before the prayer of dawn, and when you put off your garments at the noon, and after the evening prayer -- three times of nakedness for you. There is no fault in you or them, apart from these, that you go about one to the other. So God makes clear to you the signs; and God is All-knowing, All-wise. 58 And when children reach the age of puberty, let them ask permission as those before them asked permission. As such Allah makes clear to you His verses. Allah is the Knower, the Wise. 59 AND [know that] women advanced in years, who no longer feel any sexual desire, incur no sin if they discard their [outer] garments, provided they do not aim at a showy display of [their] charms. But [even so,] it is better for them to abstain [from this]: and God is all-hearing, all-knowing. 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
