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 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 No blame is there upon the blind nor any blame upon the lame nor any blame upon the sick nor on yourselves if ye eat from 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) whereof ye hold the keys, or (from the house) of a friend. No sin shall it be for you whether ye eat together or apart. But when ye enter houses, salute one another with a greeting from Allah, blessed and sweet. Thus Allah maketh clear His revelations for you, that haply ye may understand. 61
