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 When your children become mature, they must ask your permission before entering your house, as the rest of the mature people do. Thus does God explain to you His revelations. 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 It is no fault in the blind nor in one born lame, nor in one afflicted with illness, nor in yourselves, that ye should eat in your own houses, or those of your fathers, or your mothers, or your brothers, or your sisters, or your father's brothers or your father's sisters, or your mother's brothers, or your mother's sisters, or in houses of which the keys are in your possession, or in the house of a sincere friend of yours: there is no blame on you, whether ye eat in company or separately. But if ye enter houses, salute each other - a greeting of blessing and purity as from Allah. Thus does Allah make clear the signs to you: that ye may understand. 61
