Hadith 2035171 - وَ سَأَلَ سَمَاعَةُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ : عَنْ قَوْلِ اَللَّهِ عَزَّ وَ جَلَّ وَ مَنْ يَقْتُلْ مُؤْمِناً مُتَعَمِّداً فَجَزٰاؤُهُ جَهَنَّمُ قَالَ "مَنْ قَتَلَ مُؤْمِناً عَلَى دِينِهِ فَذَاكَ اَلْمُتَعَمِّدُ اَلَّذِي، قَالَ اَللَّهُ عَزَّ وَ جَلَّ فِي كِتَابِهِ وَ أَعَدَّ لَهُ عَذَاباً عَظِيماً" قُلْتُ فَالرَّجُلُ يَقَعُ بَيْنَهُ وَ بَيْنَ اَلرَّجُلِ شَيْءٌ فَيَضْرِبُهُ بِسَيْفِهِ فَيَقْتُلُهُ قَالَ "لَيْسَ ذَاكَ اَلْمُتَعَمِّدَ اَلَّذِي قَالَ اَللَّهُ عَزَّ وَ جَلَّ".
Hadith.5171 - Samaah asked Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq (as) about the saying of Allah (swt), the Almighty and Majestic:
"And whoever kills a believer intentionally, his recompense is Hell" (Surah An-Nisa 4:93).
Imam (as) said: "Whoever kills a believer because of his faith, that is the intentional killer whom Allah (swt), the Almighty and Majestic, mentioned in His (swt) Book and for whom He (swt) has prepared a great punishment."
I asked: "What about a man who has a dispute with another man, and in the heat of the moment strikes him with a sword and kills him?"
Imam (as) said: "That is not the intentional killing that Allah (swt), the Almighty and Majestic, referred to."
