The believers are only those who accept faith in Allah and His Noble Messenger and when they are present with the Noble Messenger upon being gathered for some task, do not go away until they have taken his permission; indeed those who seek your permission, are those who believe in Allah and His Noble Messenger; so if they seek your permission for some affair of theirs, give the permission to whomever you wish among them, and seek Allah’s forgiveness for them; indeed Allah is Oft Forgiving, Most Merciful.
