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 the children among you reach puberty, let them ask permission [at all times] as those before them have done. Thus does Allah make clear to you His verses; and Allah is Knowing and 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 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
