that the Messenger of Allah ﷺ said: "The adulterer is not a believer while he is committing adultery, and the thief is not a believer while he is stealing, but there is a chance for repentance; (if he repents, Allah will accept the repentance)."
قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَزْنِي الزَّانِي حِينَ يَزْنِي وَهُوَ مُؤْمِنٌ وَلاَ يَسْرِقُ السَّارِقُ حِينَ يَسْرِقُ وَهُوَ مُؤْمِنٌ وَلَكِنِ التَّوْبَةُ مَعْرُوضَةٌ وَفِي الْبَابِ عَنِ ابْنِ عَبَّاسٍ وَعَائِشَةَ وَعَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى
The Prophet ﷺ said, "When (a person) an adulterer commits illegal sexual intercourse then he is not a believer at the time he is doing it; and when somebody steals, then he is not a believer at the time he is stealing."
عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَزْنِي الزَّانِي حِينَ يَزْنِي وَهْوَ مُؤْمِنٌ وَلاَ يَسْرِقُ حِينَ يَسْرِقُ وَهْوَ مُؤْمِنٌ
The Prophet ﷺ said, "The one who commits an illegal sexual intercourse is not a believer at the time of committing illegal sexual intercourse and a thief is not a believer at the time of committing theft and a drinker of alcoholic drink is not a believer at the time of drinking. Yet, (the gate of) repentance is open thereafter."
قَالَ النَّبِيُّ ﷺ لاَ يَزْنِي الزَّانِي حِينَ يَزْنِي وَهْوَ مُؤْمِنٌ وَلاَ يَسْرِقُ حِينَ يَسْرِقُ وَهْوَ مُؤْمِنٌ وَلاَ يَشْرَبُ حِينَ يَشْرَبُهَا وَهْوَ مُؤْمِنٌ وَالتَّوْبَةُ مَعْرُوضَةٌ بَعْدُ
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)
قَالَ رَسُولُ اللَّهِ ﷺ «لَا يَسْرِقُ السَّارِقُ حِينَ يَسْرِقُ وَهُوَ مُؤْمِنٌ وَلَا يَشْرَبُ الْخَمْرَ حِينَ يَشْرَبُهَا وَهُوَ مُؤْمِنٌ وَلَكِنْ أَبْوَابُ التَّوْبَةِ مَعْرُوضَةٌ»
The Prophet ﷺ said, "The one who commits an illegal sexual intercourse is not a believer at the time of committing illegal sexual intercourse and a thief is not a believer at the time of committing theft and a drinker of alcoholic drink is not a believer at the time of drinking. Yet, (the gate of) repentance is open thereafter." (Using translation from Bukhārī 6810)
عَنِ النَّبِيِّ ﷺ قَالَ «لَا يَسْرِقُ السَّارِقُ حِينَ يَسْرِقُ وَهُوَ مُؤْمِنٌ وَلَا يَزْنِي الزَّانِي حِينَ يَزْنِي وَهُوَ مُؤْمِنٌ وَلَا يَشْرَبُ الْخَمْرَ حِينَ يَشْرَبُهَا وَهُوَ مُؤْمِنٌ وَالتَّوْبَةُ مَعْرُوضَةٌ بَعْدُ»
"لا يَزْنِي الزَّانِي حينَ يَزْنِي وهو مؤمِنٌ، ولا يَسرقُ السارقُ حين يسرقُ وهو مؤمنٌ، ولا يشربُ الخمرَ حين يشربُها وهو مؤمن، والتوبة معروضة بعد".
