[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 Surely, whatever is in the heavens and on the earth belongs to God. God knows well what condition you are in. On the Day when they return to Him, He will declare to them all that they have done. God has full knowledge of all things. 64
