Arabic (Original)
حَدَّثَنَا وَكِيعٌ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نَافِعٍ عَنْ أَبِيهِ عَنِ ابْنِ عُمَرَ قَالَ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ إِخْصَاءِ الْخَيْلِ وَالْبَهَائِمِ و قَالَ ابْنُ عُمَرَ فِيهَا نَمَاءُ الْخَلْقِ.
English Translation
Waki' told us, 'Abdullah ibn Nafi' told us, from his father, from Ibn 'Umar, who said: The Messenger of God, peace and blessings be upon him, forbade the gelding of horses and animals. Ibn 'Umar said, "In it is the increase of creation."
