[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 Place not the apostle's calling among you on the same footing as your calling of each other. Of a surety Allah knoweth those who slip away privately; let therefore those who oppose His commandment beware lest there befall them a trial or there befall them a torment afflictive. 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
