وَ رَوَى اَلْفَضْلُ بْنُ عَبْدِ اَلْمَلِكِ عَنْهُ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: "إِذَا ضَرَبَ اَلرَّجُلُ بِالْحَدِيدَةِ فَذَلِكَ اَلْعَمْدُ" قَالَ وَ سَأَلْتُهُ عَنِ اَلْخَطَإِ اَلَّذِي فِيهِ اَلدِّيَةُ وَ اَلْكَفَّارَةُ أَ هُوَ اَلرَّجُلُ يَضْرِبُ اَلرَّجُلَ فَلاَ يَتَعَمَّدُ قَتْلَهُ قَالَ "نَعَمْ" قُلْتُ فَإِذَا رَمَى شَيْئاً فَأَصَابَ رَجُلاً قَالَ "ذَلِكَ اَلْخَطَأُ اَلَّذِي لاَ يُشَكُّ فِيهِ وَ عَلَيْهِ كَفَّارَةٌ وَ دِيَةٌ".
Al-Fadl ibn Abd Al-Malik narrated from Imam (a.s) that he said: "If a man strikes with an iron weapon, that is considered intentional killing (Al-'amd)." He said: "I asked Imam (a.s) about accidental killing (khata) for which blood money (diyyah) and expiation (kaffarah) are required - would this include a man who strikes another without intending to kill him? Imam (a.s) replied: "Yes." I then asked: "What if he throws something and it hits a man?" Imam (a.s) said: "That is unquestionably accidental killing, and it requires both expiation and blood money."
