Indeed the faithful are those who have faith in Allah and His Apostle, and when they are with him in a collective affair, they do not leave until they have sought his permission. Indeed those who seek your permission —it is they who have faith in Allah and His Apostle. So when they seek your permission for some work of theirs, give permission to whomever of them you wish and plead with Allah to forgive them. Indeed Allah is all-forgiving, all-merciful.
