Regarding The Gravity Of Killing A Believer
Sunan Abi Dawud
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَمْرٍو، عَنْ مُحَمَّدِ بْنِ مُبَارَكٍ، حَدَّثَنَا صَدَقَةُ بْنُ خَالِدٍ، أَوْ غَيْرُهُ قَالَ قَالَ خَالِدُ بْنُ دِهْقَانَ سَأَلْتُ يَحْيَى بْنَ يَحْيَى الْغَسَّانِيَّ عَنْ قَوْلِهِ " اعْتَبَطَ بِقَتْلِهِ " . قَالَ الَّذِينَ يُقَاتِلُونَ فِي الْفِتْنَةِ فَيَقْتُلُ أَحَدُهُمْ فَيَرَى أَنَّهُ عَلَى هُدًى لاَ يَسْتَغْفِرُ اللَّهَ - يَعْنِي - مِنْ ذَلِكَ . قَالَ أَبُو دَاوُدَ وَقَالَ فَاعْتَبَطَ يَصُبُّ دَمَهُ صَبًّا .
Khalid b. Dihqan said: I asked Yahya b. Yahya al-Ghassani about the word i'tabata bi qatlihi spoken by him (as mentioned in the previous tradition). He said: It means those people who fight during the period of commotion (fitnah), and one of them kills (the other people) presuming that he is in the right, so he does not beg pardon of Allah of that (sin). Abu Dawud said: And he said: The word fa'tabata means "he shed blood profusely"
