Punishment of murdering someone
Thawāb al-Aʿmāl wa ʿiqāb al-Aʿmāl|Volume 1|Book 3|Chapter 126
وَ بِهَذَا الْإِسْنَادِ عَنِ ابْنِ أَبِی عُمَیْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِیِّ عَنْ أَبِی عَبْدِ اللَّهِ ع قَالَ قَالَ رَسُولُ اللَّهِ ص إِنَّ أَعَقَّ النَّاسِ عَلَی اللَّهِ تَعَالَی مَنْ قَتَلَ غَیْرَ قَاتِلِهِ وَ مَنْ ضَرَبَ مَنْ لَمْ یَضْرِبْهُ.
7. Imam Ja’far Sadiq عليه السلام said, “A person most unjust in Allah’s eyes is one who kills a person who hasn’t murdered him or hurt one who did not hurt him.”
