No Retaliation Is To Be Carried Out If A Muslim Kills A Disbeliever

It was narrated from 'Aishah, the Mother of the Believers, that the Messenger of Allah said:

"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."

أَخْبَرَنَا أَحْمَدُ بْنُ حَفْصِ بْنِ عَبْدِ اللَّهِ، قَالَ حَدَّثَنِي أَبِي قَالَ، حَدَّثَنِي إِبْرَاهِيمُ، عَنْ عَبْدِ الْعَزِيزِ بْنِ رُفَيْعٍ، عَنْ عُبَيْدِ بْنِ عُمَيْرٍ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، 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 عَزَّ وَجَلَّ وَرَسُولَهُ فَيُقْتَلُ أَوْ يُصَلَّبُ أَوْ يُنْفَى مِنَ الأَرْضِ " .

It was narrated that Ash-Sha'bi said:

"I heard Abu Juhaifah say: 'We asked 'Ali: "Do you have anything from the Messenger of Allah apart from the Qur'an?" He said: "No, by the One who splits the seeds and creates the soul, unless Allah gives a slave understanding of His Book, or except this sheet." I said: "What is in the sheet?" He said: "In it are (the regulations concerning) blood money and the freeing of captives and (the rule) that no Muslim should be killed for killing a disbeliever."

أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مُطَرِّفِ بْنِ طَرِيفٍ، عَنِ الشَّعْبِيِّ، قَالَ سَمِعْتُ أَبَا جُحَيْفَةَ، يَقُولُ سَأَلْنَا عَلِيًّا فَقُلْنَا هَلْ عِنْدَكُمْ مِنْ رَسُولِ اللَّهِ ﷺ شَىْءٌ سِوَى الْقُرْآنِ فَقَالَ لاَ وَالَّذِي فَلَقَ الْحَبَّةَ وَبَرَأَ النَّسَمَةَ إِلاَّ أَنْ يُعْطِيَ اللَّهُ عَزَّ وَجَلَّ عَبْدًا فَهْمًا فِي كِتَابِهِ أَوْ مَا فِي هَذِهِ الصَّحِيفَةِ . قُلْتُ وَمَا فِي الصَّحِيفَةِ قَالَ فِيهَا " الْعَقْلُ وَفِكَاكُ الأَسِيرِ وَأَنْ لاَ يُقْتَلَ مُسْلِمٌ بِكَافِرٍ " .

It was narrated that Abi Hassan said:

"Ali said: 'The Messenger of Allah did not tell me anything that he did not tell the people, except what is in a sheet in the sheath of my word.' They did not leave him alone until he brought out the sheet, and in it (were the words): 'The lives of the believers are equal in value, and they hasten to support the asylum granted by the least of them, and they are one against others. But no believer may be killed in return for a disbeliever, nor one with a covenant while his covenant is in effect."

أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا الْحَجَّاجُ بْنُ مِنْهَالٍ، قَالَ حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ أَبِي حَسَّانَ، قَالَ قَالَ عَلِيٌّ مَا عَهِدَ إِلَىَّ رَسُولُ اللَّهِ ﷺ بِشَىْءٍ دُونَ النَّاسِ إِلاَّ فِي صَحِيفَةٍ فِي قِرَابِ سَيْفِي . فَلَمْ يَزَالُوا بِهِ حَتَّى أَخْرَجَ الصَّحِيفَةَ فَإِذَا فِيهَا " الْمُؤْمِنُونَ تَكَافَأُ دِمَاؤُهُمْ يَسْعَى بِذِمَّتِهِمْ أَدْنَاهُمْ وَهُمْ يَدٌ عَلَى مَنْ سِوَاهُمْ لاَ يُقْتَلُ مُؤْمِنٌ بِكَافِرٍ وَلاَ ذُو عَهْدٍ فِي عَهْدِهِ " .
