O you who have believed, let those whom your right hands possess and those who have not [yet] reached puberty among you ask permission of you [before entering] at three times: before the dawn prayer and when you put aside your clothing [for rest] at noon and after the night prayer. [These are] three times of privacy for you. There is no blame upon you nor upon them beyond these [periods], for they continually circulate among you - some of you, among others. Thus does Allah make clear to you the verses; and Allah is Knowing and Wise. 58 And when the children among you come to puberty, then let them (also) ask for permission, as those senior to them (in age). Thus Allah makes clear His Ayat (Commandments and legal obligations) for you. And Allah is All-Knowing, 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 no harm if a blind or a lame or a sick person (takes a meal at another's house): nor is there any harm for yourselves if you take meals at your own houses or at the houses of your fathers and grandfathers or at the houses of your mothers and grandmothers or at your brothers' houses or at your sisters' houses or at the houses of your paternal uncles or at the houses of your paternal aunts or at the houses of your maternal uncles or at the houses of your maternal aunts or from the houses whose keys are in your possession or at the houses of your friends. There is no harm if you take your meals together or separately; however, when you enter the houses, you should send greetings of peace on your people, for the prayer of greetings prescribed by Allah is blessed and pure. Thus Allah makes His Revelation's clear to you. It is expected that you will use your common sense to grasp these. 61
