[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 Make not the calling of the Messenger among yourselves like your calling one of another. God knows those of you who slip away surreptitiously; so let those who go against His command beware, lest a trial befall them, or there befall them a painful chastisement. 63 Pay heed! Indeed to Allah only belong whatsoever is in the heavens and in the earth; He knows the condition you are in; and on the Day when they are returned to Him, He will then inform them of whatever they did; and Allah knows all things. 64
