O you who have believed, let those whom your right hands possess and those who have not [yet] reached puberty among you ask permission of you [before entering] at three times: before the dawn prayer and when you put aside your clothing [for rest] at noon and after the night prayer. [These are] three times of privacy for you. There is no blame upon you nor upon them beyond these [periods], for they continually circulate among you - some of you, among others. Thus does Allah make clear to you the verses; and Allah is Knowing and 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 And the old women residing in houses who do not have the desire of marriage – it is no sin upon them if they discard their upper coverings provided they do not display their adornment; and avoiding even this is better for them; and Allah is All Hearing, All Knowing. 60 No restriction is there upon the blind, nor is there the restriction upon a lame, nor is there a restriction upon the sick, nor upon yourselves that ye eat in 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 house whereof ye own the keys or from the house of a friend. No fault is there upon you whether ye eat together or in separate groups. Then when ye enter houses, salute each other with a greeting from before Allah, blest and goodly. Thus Allah expoundeth unto you the revelations, haply ye may reflect. 61
