[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 Do not consider your being summoned by the Apostle to be like your summoning one another. God knows those of you who go away surreptitiously. So let those who act in contravention of his command take heed lest a trial should befall them or a grievous punishment come upon them. 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
