(16) باب الدَّلِيلِ عَلَى زِيَادَةِ الإِيمَانِ وَنُقْصَانِهِ
Abu Hurairah reported the Messenger of Allah (May peace be upon him) as saying :
When one commits fornication, one is not a believer ; when one steals, one is not a believer ; when one drinks, one is not a believer ; and repentance is placed before him.
