[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 The heavens and the earth, certainly, belong to God. He surely knows all about you in this life. On the day when you return to Him, He will tell you all about whatever you have done. God has the knowledge of all things. 64
