his grandfather came to the Prophet ﷺ and he had castrated a slave of his. The Prophet ﷺ manumitted the slave in compensation for having been mutilated.  

أَنَّهُ قَدِمَ عَلَى النَّبِيِّ ﷺ وَقَدْ خَصَى غُلاَمًا لَهُ فَأَعْتَقَهُ النَّبِيُّ ﷺ بِالْمُثْلَةِ  

“A man came to the Prophet ﷺ screaming. The Messenger of Allah ﷺ said to him: 'What is the matter with you?' He said: 'My master saw me kissing a slave woman of his, so he cut off my penis.' The Prophet ﷺ said: 'Take me to the man.' He was sought but could not be found, so the Messenger of Allah ﷺ said: 'Go, for you are free.' He said: 'Who will protect me, O Messenger of Allah ﷺ? What if my master enslaves me again?' The Messenger of Allah ﷺ said: 'Your protection will be (incumbent upon) every believer or Muslim.'”  

جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ صَارِخًا فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ مَا لَكَ قَالَ سَيِّدِي رَآنِي أُقَبِّلُ جَارِيَةً لَهُ فَجَبَّ مَذَاكِيرِي فَقَالَ النَّبِيُّ ﷺ عَلَىَّ بِالرَّجُلِ فَطُلِبَ فَلَمْ يُقْدَرْ عَلَيْهِ فَقَالَ رَسُولُ اللَّهِ ﷺ اذْهَبْ فَأَنْتَ حُرٌّ قَالَ عَلَى مَنْ نُصْرَتِي يَا رَسُولَ اللَّهِ قَالَ يَقُولُ أَرَأَيْتَ إِنِ اسْتَرَقَّنِي مَوْلاَىَ فَقَالَ رَسُولُ اللَّهِ ﷺ عَلَى كُلِّ مُؤْمِنٍ أَوْ مُسْلِمٍ
