The believers are those alone who have believed in Allah and His apostle, and when they are with him on some affair collecting people together they depart not until they have asked his leave. Verily those who ask thy leave, those are they who believe in Allah and His apostle. So if they ask thy leave for some business of theirs, give thou leave unto whomsoever of them thou wilt, and ask thou forgiveness of Allah for them. Verily Allah is Forgiving, Merciful. 62 Do not address the Messenger as you would call each other. God knows those who secretly walk away from you and hide themselves. Those who oppose the Messengers should beware, lest some trouble or a painful torment should befall them. 63 Beware! whatever is in the heavens and the earth belongs to Allah. He knows whatever you are doing. On the Day you shall return to Him, He will let you know what you have. done: He has full knowledge of everything. 64
