The fornicator who fornicates is not a believer so long as he commits it and no thief who steals is a believer as long as he commits theft, and no drunkard who drinks wine is a believer as long as he drinks it. 'Abdul-Malik b. Abi Bakr' narrated this on the authority of Abu Bakr b. Abdur-Rahman b. Harith and then said: Abu Huraira made this addition: No plunderer who plunders a valuable thing that attracts the attention of people is a believer so long as he commits this act.
أَبُو هُرَيْرَةَ إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَزْنِي الزَّانِي حِينَ يَزْنِي وَهُوَ مُؤْمِنٌ وَلاَ يَسْرِقُ السَّارِقُ حِينَ يَسْرِقُ وَهُوَ مُؤْمِنٌ وَلاَ يَشْرَبُ الْخَمْرَ حِينَ يَشْرَبُهَا وَهُوَ مُؤْمِنٌ قَالَ ابْنُ شِهَابٍ فَأَخْبَرَنِي عَبْدُ الْمَلِكِ بْنُ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ أَنَّ أَبَا بَكْرٍ كَانَ يُحَدِّثُهُمْ هَؤُلاَءِ عَنْ أَبِي هُرَيْرَةَ ثُمَّ يَقُولُ وَكَانَ أَبُو هُرَيْرَةَ يُلْحِقُ مَعَهُنَّ وَلاَ يَنْتَهِبُ نُهْبَةً ذَاتَ شَرَفٍ يَرْفَعُ النَّاسُ إِلَيْهِ فِيهَا أَبْصَارَهُمْ حِينَ يَنْتَهِبُهَا وَهُوَ مُؤْمِنٌ
