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 When your children have reached the age of puberty, let them still ask permission as their elders do. Thus God expounds to you His revelations: God is all knowing and 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 There is no fault in the blind, and there is no fault in the lame, and there is no fault in the sick, neither in yourselves, that you eat of your houses, or your fathers' houses, or your mothers' houses, or your brothers' houses, or your sisters' houses, or the houses of your uncles or your aunts paternal, or the houses of your uncles or your aunts maternal, or that whereof you own the keys, or of your friend; there is no fault in you that you eat all together, or in groups separately. But when you enter houses, greet one another with a greeting from God, blessed and good. So God makes clear to you the signs; haply you will understand. 61
