[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 treat being called by the Messenger like being called by one another. God knows those of you who slip away on some pretext. Let those who go against his order beware lest some affliction befall them or they receive a painful punishment. 63 Now surely Allah's is whatever is in the heavens and the earth; He knows indeed that to which you are conforming yourselves; and on the day on which they are returned to Him He will inform them of what they did; and Allah is Cognizant of all things. 64
