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
