Sahih Muslim 7023

حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ حَدَّثَنَا عَفَّانُ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ أَخْبَرَنَا ثَابِتٌ عَنْ أَنَسٍ أَنَّ رَجُلًا كَانَ يُتَّهَمُ بِأُمِّ وَلَدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِعَلِيٍّ اذْهَبْ فَاضْرِبْ عُنُقَهُ فَأَتَاهُ عَلِيٌّ فَإِذَا هُوَ فِي رَكِيٍّ يَتَبَرَّدُ فِيهَا فَقَالَ لَهُ عَلِيٌّ اخْرُجْ فَنَاوَلَهُ يَدَهُ فَأَخْرَجَهُ فَإِذَا هُوَ مَجْبُوبٌ لَيْسَ لَهُ ذَكَرٌ فَكَفَّ عَلِيٌّ عَنْهُ ثُمَّ أَتَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّهُ لَمَجْبُوبٌ مَا لَهُ ذَكَرٌ

Anas reported that a person was charged with fornication with the slavegirl of Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). Thereupon Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said to 'Ali: Go and strike his neck. 'Ali came to him and he found him in a well making his body cool. 'Ali said to him: Come out, and as he took hold of his hand and brought him out, he found that his sexual organ had been cut. Hadrat 'Ali refrained from striking his neck. He came to Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and said: Allah's Messenger, he has not even the sexual organ with him.
