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 no restriction on the blind, nor any restriction on the lame, nor any restriction on the sick, nor on yourselves, if you 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 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 that) whereof you hold keys, or (from the house) of a friend. No sin on you whether you eat together or apart. But when you enter the houses, greet one another with a greeting from Allah (i.e. say: As-Salamu 'Alaikum - peace be on you) blessed and good. Thus Allah makes clear the Ayat (these Verses or your religious symbols and signs, etc.) to you that you may understand. 61
