They only are true believers who believe in God and His Messenger. When they are with him on some matter of common concern, they should not depart until they have asked him for permission to do so. Those who ask you for such permission are the ones who truly believe in God and His Messenger. When they ask you for permission to attend to some affair of their own, then grant it to whoever you please and seek forgiveness from God for them. God is forgiving and 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
