It was narrated that Samurah said:"The Prophet said: 'Whoever kills his slave, we will kill him, and whoever mutilates his slave, we will mutilate him."'
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ سَمُرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ قَتَلَ عَبْدَهُ قَتَلْنَاهُ وَمَنْ جَدَعَ عَبْدَهُ جَدَعْنَاهُ " .
