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 address the Messenger as you would call each other. God knows those who secretly walk away from you and hide themselves. Those who oppose the Messengers should beware, lest some trouble or a painful torment should befall them. 63 Oh, verily, unto God belongs all that is in the heavens and on earth: well does He know where you stand and at what you aim! And one Day, all [who have ever lived] will be brought back unto Him, and then He will make them [truly] understand all that they were doing [in life]: for, God has full knowledge of everything. 64
