Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 36
وَ رَوَى اَلْحَسَنُ بْنُ عَلِيِّ بْنِ فَضَّالٍ عَنْ يُونُسَ بْنِ يَعْقُوبَ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْإِخْصَاءِ فَلَمْ يُجِبْنِي، فَسَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنْ ذَلِكَ فَقَالَ "لاَ بَأْسَ بِهِ".
It is narrated by Al-Hasan ibn Ali ibn Fadhal, from Yunus ibn Ya'qub, who said: I asked Abu Abdullah عليه السلام, about castration, but Imam عليه السلام did not answer me. Then I asked Abu Al-Hasan عليه السلام about it, and Imam عليه السلام said: "There is no harm in it."
