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 as for women past child-bearing who do not expect wed-lock, it is no sin on them if they discard their (outer) clothing in such a way as not to show their adornment. But to refrain (i.e. not to discard their outer clothing) is better for them. And Allah is All-Hearer, All-Knower. 60 No restriction is there upon the blind, nor is there the restriction upon a lame, nor is there a restriction upon the sick, nor upon yourselves that ye eat in 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 house whereof ye own the keys or from the house of a friend. No fault is there upon you whether ye eat together or in separate groups. Then when ye enter houses, salute each other with a greeting from before Allah, blest and goodly. Thus Allah expoundeth unto you the revelations, haply ye may reflect. 61
