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. 62 DO NOT regard the Apostle's summons to you [in the same light] as a summons of one of you to another: God is indeed aware of those of you who would withdraw surreptitiously: so let those who would go against His bidding beware, lest a [bitter] trial befall them [in this world] or grievous suffering befall them [in the life to come]. 63 Be quite sure that to Allah doth belong whatever is in the heavens and on earth. Well doth He know what ye are intent upon: and one day they will be brought back to Him, and He will tell them the truth of what they did: for Allah doth know all things. 64
