O you who believe! let those whom your right hands possess and those of you who have not attained to puberty ask permission of you three times; before the morning prayer, and when you put off your clothes at midday in summer, and after the prayer of the nightfall; these are three times of privacy for you; neither is it a sin for you nor for them besides these, some of you must go round about (waiting) upon others; thus does Allah make clear to you the communications, and Allah is Knowing, Wise. 58 When your children have reached the age of puberty, they should similarly ask your leave (for entering) as others did before them. God thus clearly explains His commands to you, for God is all-knowing and all-wise. 59 And (as for) women advanced in years who do not hope for a marriage, it is no sin for them if they put off their clothes without displaying their ornaments; and if they restrain themselves it is better for them; and Allah is Hearing, Knowing. 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
