Mishkat al-Masabih 16 Retaliation كتاب القصاص 34

وَعَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِذَا أَمْسَكَ الرَّجُلُ الرَّجُلَ وَقَتَلَهُ الْآخَرُ يُقْتَلُ الَّذِي قتَل ويُحبسُ الَّذِي أمْسَكَ» . رَوَاهُ الدَّارَقُطْنِيّ

Ibn ‘Umar reported the Prophet as saying, “If a man seizes a man and another kills him, the one who killed him is to be killed and the one who seized him is to be imprisoned.” Daraqutni transmitted it.
