O you who believe, let your dependants and those who have not yet reached the age of puberty, ask permission (to enter your presence) on three occasions: Before the early morning prayer; when you disrobe for the mid-day siesta; and after prayer at night. These are the three occasions of dishabille for you. There is no harm if you or they visit one another at other times (without permission). God thus explains things to you clearly, for God is all-knowing and all-wise. 58 And when the children among you attain puberty, then let them ask leave even as those before them asked leave. In this wise Allah expoundeth unto you His commandments; and Allah is Knowing, Wise. 59 Such elderly women as are past the prospect of marriage,- there is no blame on them if they lay aside their (outer) garments, provided they make not a wanton display of their beauty: but it is best for them to be modest: and Allah is One Who sees and knows all things. 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
