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 boys among you reach adulthood, then they too must seek permission like those before them had sought; this is how Allah explains His verses for you; and Allah is All Knowing, Wise. 59 Such elderly women as are past the prospect of marriage,- there is no blame on them if they lay aside their (outer) garments, provided they make not a wanton display of their beauty: but it is best for them to be modest: and Allah is One Who sees and knows all things. 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
