Believers, your slaves and the immature people must ask your permission three times a day before entering your house: before the morning prayer, at noon time and after the late evening prayer; these are most private times. After your permission has been granted, there is no harm if they come into your presence from time to time. This is how God explains His revelations to you. 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 (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 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
