كتاب الحدود
Read the English translation first, with the original Arabic directly underneath.
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "When an adulterer commits illegal sexual intercourse, then he is not a believer at the time he is doing it; and when somebody drinks an alcoholic drink, then he is not believer at the time of drinking, and when a thief steals, he is not a believer at the time when he is stealing; and when a robber robs and the people look at him, then he is not a believer at the time of doing it." Abu Huraira in another narration, narrated the same from the Prophet (ﷺ) with the exclusion of robbery.
لاَ يَزْنِي الزَّانِي حِينَ يَزْنِي وَهْوَ مُؤْمِنٌ، وَلاَ يَشْرَبُ الْخَمْرَ حِينَ يَشْرَبُ وَهْوَ مُؤْمِنٌ، وَلاَ يَسْرِقُ حِينَ يَسْرِقُ وَهْوَ مُؤْمِنٌ، وَلاَ يَنْتَهِبُ نُهْبَةً يَرْفَعُ النَّاسُ إِلَيْهِ فِيهَا أَبْصَارَهُمْ وَهْوَ مُؤْمِنٌ
