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.  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ قَتَلَ عَبْدَهُ قَتَلْنَاهُ وَمَنْ جَدَعَ عَبْدَهُ جَدَعْنَاهُ  

Through the same chain of narrators as mentioned before, i.e. Samurah reported the Messenger of Allah ﷺ as saying: If anyone castrates his slave, we shall castrate him. He then mentioned the rest of the tradition like that of Sh'ubah and Hammad. Abu Dawud said: Abu Dawud al-Tayalisi transmitted it from Hisham like the tradition of Mu'adh.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ خَصَى عَبَدَهُ خَصَيْنَاهُ ثُمَّ ذَكَرَ مِثْلَ حَدِيثِ شُعْبَةَ وَحَمَّادٍ  

Then al-Hasan forgot this tradition, and he used to say: A free man is not to be killed for a slave.  

عَنْ قَتَادَةَ بِإِسْنَادِ شُعْبَةَ مِثْلَهُ زَادَ ثُمَّ إِنَّ الْحَسَنَ نَسِيَ هَذَا الْحَدِيثَ فَكَانَ يَقُولُ لاَ يُقْتَلُ حُرٌّ بِعَبْدٍ  

"A free man should not be subjected to retaliation in return for a slave."  

لاَ يُقَادُ الْحُرُّ بِالْعَبْدِ  

On his father's authority, said that his grandfather told that a A man came to the Prophet ﷺ crying for help. He said: His slave-girl, Messenger of Allah! He said: Woe to you, what happened with you ? He said that it was an evil one. He saw the slave-girl of his master; he became jealous of him, and cut off his penis. The Messenger of Allah ﷺ said: Bring the man to me. The man was called, but people could not get control over him. The Messenger of Allah ﷺ then said: Go away, you are free. He asked: Messenger of Allah! upon whom does my help lie? He replied: On every believer, or he said: On every Muslim. Abu Dawud said: The name of the man who was emancipated was Rawh b. Dinar Abu Dawud said: The man who cut off the penis was Zinba' Abu Dawud said: The Zinba' Abu Rawh was master of the slave.  

جَاءَ رَجُلٌ مُسْتَصْرِخٌ إِلَى النَّبِيِّ ﷺ فَقَالَ جَارِيَةٌ لَهُ يَا رَسُولَ اللَّهِ فَقَالَ وَيْحَكَ مَا لَكَ قَالَ شَرًّا أَبْصَرَ لِسَيِّدِهِ جَارِيَةً لَهُ فَغَارَ فَجَبَّ مَذَاكِيرَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ عَلَىَّ بِالرَّجُلِ فَطُلِبَ فَلَمْ يُقْدَرْ عَلَيْهِ فَقَالَ رَسُولُ اللَّهِ ﷺ اذْهَبْ فَأَنْتَ حُرٌّ فَقَالَ يَا رَسُولَ اللَّهِ عَلَى مَنْ نُصْرَتِي قَالَ عَلَى كُلِّ مُؤْمِنٍ أَوْ قَالَ كُلِّ مُسْلِمٍ
