24.61 . No blame is there upon the blind nor any blame upon the lame nor any blame upon the sick nor on yourselves if ye 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 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 ) whereof ye hold the keys , or ( from the house ) of a friend . No sin shall it be for you whether ye eat together or apart . But when ye enter houses , salute one another with a greeting from Allah , blessed and sweet . Thus Allah maketh clear His revelations for you , that haply ye may understand .

24.62 . They only are the true believers who believe in Allah and His messenger and , when they are with him on some common errand , go not away until they have asked leave of him . Lo! those who ask leave of thee , those are they who believe in Allah and His messenger . So , if they ask thy leave for some affair of theirs , give leave to whom thou wilt of them , and ask for them forgiveness of Allah . Lo! Allah is Forgiving , Merciful .

24.63 . Make not the calling of the messenger among you as your calling one of another . Allah knoweth those of you who steal away , hiding themselves . And let those who conspire to evade orders beware lest grief or painful punishment befall them .

24.64 . Lo! verily unto Allah belongeth whatsoever is in the heavens and the earth . He knoweth your condition . And ( He knoweth ) the Day when they are returned unto Him so that He may inform them of what they did . Allah is Knower of all things .
