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 When your children become mature, they must ask your permission before entering your house, as the rest of the mature people do. Thus does God explain to you His revelations. God is All-knowing and All-wise. 59 There is no sin for such elderly women as are past the age of marriage, if they lay aside their outer graments provided that they do not mean to display their adornment. Nevertheless, if they behave modestly, it would be better for them: for Allah hears everything and knows everything. 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
