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 But when the children among you come of age, let them (also) ask for permission, as do those senior to them (in age): Thus does Allah make clear His Signs to you: for Allah is full of knowledge and wisdom. 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 not upon the blind [any] constraint nor upon the lame constraint nor upon the ill constraint nor upon yourselves when you eat from your [own] 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 father's brothers or the houses of your father's sisters or the houses of your mother's brothers or the houses of your mother's sisters or [from houses] whose keys you possess or [from the house] of your friend. There is no blame upon you whether you eat together or separately. But when you enter houses, give greetings of peace upon each other - a greeting from Allah, blessed and good. Thus does Allah make clear to you the verses [of ordinance] that you may understand. 61
