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 And when your children have grown sex conscious, they should receive your permission for this just as their elders get permission. In this way Allah makes His Revelations plain to you for He is All-Knowing, AllWise. 59 AND [know that] women advanced in years, who no longer feel any sexual desire, incur no sin if they discard their [outer] garments, provided they do not aim at a showy display of [their] charms. But [even so,] it is better for them to abstain [from this]: and God is all-hearing, all-knowing. 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
