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 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 No restriction is there upon the blind, nor is there the restriction upon a lame, nor is there a restriction upon the sick, nor upon yourselves that ye eat in your houses or the houses of your fathers or the houses of your mothers or the houses of your brothers or the houses of your sisters or the houses of your fathers brothers or the houses of your fathers sisters or the houses of your mothers brothers or the houses of your mothers sisters or from that house whereof ye own the keys or from the house of a friend. No fault is there upon you whether ye eat together or in separate groups. Then when ye enter houses, salute each other with a greeting from before Allah, blest and goodly. Thus Allah expoundeth unto you the revelations, haply ye may reflect. 61
