Mishkat al-Masabih 16 Retaliation كتاب القصاص 28

وَعَن طَاوُوس عَنِ ابْنِ عَبَّاسٍ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ قُتِلَ فِي عِمِّيَّةٍ فِي رَمْيٍ يَكُونُ بَيْنَهُمْ بِالْحِجَارَةِ أَوْ جَلْدٍ بِالسِّيَاطِ أَوْ ضَرْبٍ بِعَصًا فَهُوَ خَطَأٌ عقله الْخَطَأِ وَمَنْ قَتَلَ عَمْدًا فَهُوَ قَوَدٌ وَمَنْ حَالَ دُونَهُ فَعَلَيْهِ لَعْنَةُ اللَّهِ وَغَضَبُهُ لَا يُقْبَلُ مِنْهُ صَرْفٌ وَلَا عَدْلٌ» . رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ

Ta’us, on the authority of Ibn ‘Abbas, reported God’s Messenger as saying, “If anyone is killed in error when people are throwing stones, or by beating with whips, or striking with a stick, it is accidental and the compensation for accidental death is due.* But if anyone kills someone deliberately retaliation is due, and if anyone tries to prevent it God’s curse and anger will rest on him, and neither supererogatory nor obligatory acts will be accepted from him.” Abu Dawud and Nasa’i transmitted it. *These are instances in which the actual person who killed him is not clearly known, or where there was no intention to kill.
