The believers are only those who believe in Allah and His messenger and who, when they are with him for a collective matter, do not leave unless they seek his permission. Surely, those who seek your permission are the ones who believe in Allah and His messenger. So, if they seek permission from you for some business of theirs, give permission to whom you wish from among them, and pray to Allah for their forgiveness. Surely, Allah is Most-Forgiving, Very-Merciful.
