"Whoever kills his slave, we will kill him: whoever mutilates (his slave). We will mutilate him, and whoever castrates (his slave), we will castrate him." (Using translation from Nasāʾī 4736)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنْ قَتَلَ عَبْدَهُ قَتَلْنَاهُ وَمَنْ جَدَعَهُ جَدَعْنَاهُ وَمَنْ أَخْصَاهُ أَخْصَيْنَاهُ»  

[Machine] Narrated by Abu Abdullah Al-Hasan, from Samurah, it was said that it is from the unrecorded scripture, except for the Hadith of Al-Aqiqah. Then it was said to Al-Hasan, "From whom did you hear the Hadith of Al-Aqiqah?" He replied, "From Samurah, and not every person of knowledge affirms this narration." I asked Al-Hasan, "From whom did you hear the Hadith of Al-Aqiqah?"  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ قَتَلَ عَبْدَهُ قَتَلْنَاهُ وَمَنْ جَدَعَ عَبْدَهُ جَدَعْنَاهُ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ الْحَسَنُ عَنْ سَمُرَةَ قِيلَ إِنَّهُ مِنَ الصَّحِيفَةِ غَيْرُ مَسْمُوعَةٍ إِلَّا حَدِيثَ الْعَقِيقَةِ فَإِنَّهُ قِيلَ لِلْحَسَنِ مِمَّنْ سَمِعْتَ حَدِيثَ الْعَقِيقَةِ؟ قَالَ مِنْ سَمُرَةَ وَلَيْسَ كُلُّ أَهْلِ الْعِلْمِ يُصَحِّحُ هَذِهِ الرِّوَايَةَ قَوْلَهُ قُلْتُ لِلْحَسَنِ مِمَّنْ سَمِعْتَ حَدِيثَ الْعَقِيقَةِ؟  

The Prophet ﷺ Said: If anyone kills his slave, we shall kill him, and if anyone cuts off the nose of his slave, we shall cut off his nose. (Using translation from Abū Dāʾūd 4515)  

قَالَ رَسُولُ اللهِ ﷺ «مَنْ قَتَلَ عَبْدَهُ قَتَلْنَاهُ وَمَنْ جَدَعَ عَبْدَهُ جَدَعْنَاهُ»
