[TRUE BELIEVERS are only they who have attained to faith in God and His Apostle, and who, whenever they are [engaged] with him upon a matter of concern to the whole community do not depart [from whatever has been decided upon] unless they have sought [and obtained] his leave. Verily, those who [do not abstain from the agreed upon action unless they] ask leave of thee - it is [only] they who [truly] believe in God and His Apostle! Hence, when they ask leave of thee for some [valid] reason of their own, grant thou this leave to whomsoever of them thou choose [to grant it,] and ask God to forgive them: for, behold, God is much-forgiving, a dispenser of grace! 62 O Believers, do not consider the summoning by the Messenger like the summoning among you by one another. Allah knows well those of you who steal away, concealing themselves behind others. Let those who disobey the order of the Messenger beware lest they should be involved in some affliction, or are visited by a woeful scourge. 63 Does not everything in the heavens and the earth belong to God? He surely knows what state you are in; and on the day they go back to Him. He will tell them what they used to do, for God has knowledge of everything. 64
