"It is not permissible to kill a Muslim except in one of three cases: A adulterer who has been married, who is to be stoned; a man who kills a Muslim deliberately; and a man who leaves Islam and wages war against Allah, the Mighty and Sublime, and His Messenger, who is to be killed, crucified or banished from the land."  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ لاَ يَحِلُّ قَتْلُ مُسْلِمٍ إِلاَّ فِي إِحْدَى ثَلاَثِ خِصَالٍ زَانٍ مُحْصَنٍ فَيُرْجَمُ وَرَجُلٌ يَقْتُلُ مُسْلِمًا مُتَعَمِّدًا وَرَجُلٌ يَخْرُجُ مِنَ الإِسْلاَمِ فَيُحَارِبُ اللَّهَ ﷻ وَرَسُولَهُ فَيُقْتَلُ أَوْ يُصَلَّبُ أَوْ يُنْفَى مِنَ الأَرْضِ  

The Messenger of Allah [SAW] said: "It is not permissible to shed the blood of a Muslim except in three cases: An adulterer who had been married, who should be stoned to death; a man who killed another man intentionally, who should be killed; and a man who left Islam and waged war against Allah, the Might and Sublime, and His Messenger, who should be killed, or crucified, or banished from the land."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلاَّ بِإِحْدَى ثَلاَثِ خِصَالٍ زَانٍ مُحْصَنٌ يُرْجَمُ أَوْ رَجُلٌ قَتَلَ رَجُلاً مُتَعَمِّدًا فَيُقْتَلُ أَوْ رَجُلٌ يَخْرُجُ مِنَ الإِسْلاَمِ يُحَارِبُ اللَّهَ ﷻ وَرَسُولَهُ فَيُقْتَلُ أَوْ يُصْلَبُ أَوْ يُنْفَى مِنَ الأَرْضِ  

"It is not permissible to kill a Muslim except in one of three cases: A adulterer who has been married, who is to be stoned; a man who kills a Muslim deliberately; and a man who leaves Islam and wages war against Allah, the Mighty and Sublime, and His Messenger, who is to be killed, crucified or banished from the land." (Using translation from Nasāʾī 4743)  

عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ لَا يَحِلُّ قَتْلُ مُسْلِمٍ إِلَّا فِي إِحْدَى ثَلَاثِ خِصَالٍ زَانٍ مُحْصَنٍ فَيُرْجَمُ وَرَجُلٌ يَقْتُلُ مُسْلِمًا مُتَعَمِّدًا فَيُقْتَلُ وَرَجُلٌ يَخْرُجُ مِنَ الْإِسْلَامِ فَيُحَارِبُ اللهَ وَرَسُولَهُ فَيُقْتَلُ أَوْ يُصْلَبُ أَوْ يُنْفَى مِنَ الْأَرْضِ  

The Messenger of Allah [SAW] said: "It is not permissible to shed the blood of a Muslim except in three cases: An adulterer who had been married, who should be stoned to death; a man who killed another man intentionally, who should be killed; and a man who left Islam and waged war against Allah, the Might and Sublime, and His Messenger, who should be killed, or crucified, or banished from the land." (Using translation from Nasāʾī 4048)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَحِلُّ دَمَ امْرِئٍ مُسْلِمٍ إِلَّا بِإِحْدَى ثَلَاثِ خِصَالٍ زَانٍ مِحْصَنٌ يُرْجَمُ أَوْ رَجُلٌ قَتَلَ رَجُلًا مُتَعَمِّدًا فَيُقْتَلُ أَوْ رَجُلٌ يَخْرُجُ مِنَ الْإِسْلَامِ لِيُحَارِبَ اللهَ ﷻّ وَرَسُولَهُ فَيُقْتَلُ أَوْ يُصْلَبُ أَوْ يُنْفَى مِنَ الْأَرْضِ  

The Messenger of Allah ﷺ Said: The blood of a Muslim man who testifies that there is no god but Allah and that Muhammad is Allah's Apostle should not lawfully be shed except only for one of three reasons: a man who committed fornication after marriage, in which case he should be stoned; one who goes forth to fight with Allah and His Apostle, in which case he should be killed or crucified or exiled from the land; or one who commits murder for which he is killed. (Using translation from Abū Dāʾūd 4353)   

قَالَ رَسُولُ اللهِ ﷺ لَا يَحِلُّ قَتْلُ امْرِئٍ مُسْلِمٍ يَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ وَأَنِّي رَسُولُ اللهِ إِلَّا فِي إِحْدَى ثَلَاثٍ زَانٍ بَعْدَ إِحْصَانٍ وَرَجُلٌ قَتَلَ يُقْتَلُ بِهِ وَرَجُلٌ خَرَجَ مُحَارِبًا لِلَّهِ وَرَسُولِهُ فَيُقْتَلُ أَوْ يُصْلَبُ أَوْ يُنْفَى مِنَ الْأَرْضِ  

"لَا يَحِلُّ دَمُ امْرِيءٍ مُسْلِمٍ يَشْهَدُ أَن لا إِلَهَ إلا الله، وَأَنَّ مُحَمدًا رَسُولُ الله، إلا بِإِحْدَى ثَلَاثٍ: رَجُلٌ زَنَى بَعْدَ إِحصَانٍ فَإِنَّهُ يُرجَمُ، وَرَجُل خَرَجَ مُحَارِبًا لله وَرَسُولِهِ، فَإِنَّهُ يُقْتَلُ أَوْ يُصْلَبُ وَيُنْفَى مِنَ الأَرْض، أَوْ يَقْتَلُ نَفْسًا فَيُقْتَلُ بِهَا".
