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 women of post-menstrual age who have no desire for marriage - there is no blame upon them for putting aside their outer garments [but] not displaying adornment. But to modestly refrain [from that] is better for them. And Allah is Hearing and Knowing. 60 There is no harm if the blind, the lame, the sick or you yourselves eat in your own houses, or in the houses of your fathers, or mothers, or brothers, or sisters, or paternal uncles, or paternal aunts, or maternal uncles, or maternal aunts, or in those that you are in charge of or in the house of a friend. There is no objection to your eating together or separately. But when you enter houses, salute one another with a greeting of peace, a greeting from your Lord full of blessings and purity. Thus does God expound to you His commandments, so that you may understand. 61
