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 have reached the age of puberty, let them still ask permission as their elders do. Thus God expounds to you His revelations: God is all 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 There is not upon the blind [any] constraint nor upon the lame constraint nor upon the ill constraint nor upon yourselves when you eat from your [own] 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 father's brothers or the houses of your father's sisters or the houses of your mother's brothers or the houses of your mother's sisters or [from houses] whose keys you possess or [from the house] of your friend. There is no blame upon you whether you eat together or separately. But when you enter houses, give greetings of peace upon each other - a greeting from Allah, blessed and good. Thus does Allah make clear to you the verses [of ordinance] that you may understand. 61
