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.
