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 (a.s), about castration, but Imam (a.s) did not answer me. Then I asked Abu Al-Hasan (a.s) about it, and Imam (a.s) said: "There is no harm in it."
