The Prophet ﷺ said: If anyone kills a man whom he grants protection prematurely, Allah will forbid him to enter Paradise. (Using translation from Abū Dāʾūd 2760)  

قَالَ رَسُولُ اللهِ ﷺ «مَنْ قَتَلَ مُعَاهِدًا فِي غَيْرِ كُنْهِهِ حَرَّمَ اللهُ عَلَيْهِ الْجَنَّةَ»  

The Messenger of Allah said: "Whoever kills a Mu'ahad with no justification, Allah will forbid Paradise to him and he will not even smell its fragrance." (Using translation from Nasāʾī 4748)  

قَالَ رَسُولُ اللهِ ﷺ «مَنْ قَتَلَ نَفْسًا مُعَاهِدًا بِغَيْرِ حِلِّهَا حَرَّمَ اللهُ عَلَيْهِ الْجَنَّةَ أَنْ يَشُمَّ رِيحَهَا»  

"Whoever kills a man from among Ahl Adh-Dhimmah.[2] he will not smell the fragrance of Paradise, and its fragrance may be detected from a distance of seventy years." (Using translation from Nasāʾī 4749)  

عَنْ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنْ قَتَلَ رَجُلًا مِنْ أَهْلِ الذِّمَّةِ لَمْ يَجِدْ رِيحَ الْجَنَّةِ وَإِنَّ رِيحَهَا لَيُوجَدُ مِنْ مَسِيرَةِ سَبْعِينَ عَامًا»  

"The Messenger of Allah said: 'Whoever kills a person from among Ahl Adh-Dhimmah, he will not smell the fragrance of Paradise, and its fragrance may be detected from a distance of forty years." (Using translation from Nasāʾī 4750)  

قَالَ رَسُولُ اللهِ ﷺ «مَنْ قَتَلَ قَتِيلًا مِنْ أَهْلِ الذِّمَّةِ لَمْ يَجِدْ رِيحَ الْجَنَّةِ وَإِنَّ رِيحَهَا لَيُوجَدُ مِنْ مَسِيرَةِ أَرْبَعِينَ عَامًا»
