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. (Using translation from Abū Dāʾūd 4689)
«لَا يَزْنِي الزَّانِي حِينَ يَزْنِي وَهُوَ مُؤْمِنٌ وَلَا يَسْرِقُ حِينَ يَسْرِقُ وَهُوَ مُؤْمِنٌ وَلَا يَشْرَبُ الْخَمْرَ حِينَ يَشْرَبُهَا وَهُوَ مُؤْمِنٌ»
