Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنِ ابْنِ جُرَيْجٍ قَالَ أَخْبَرَنِي عَطَاءٌ قَالَ أَخْبَرَنِي صَفْوَانُ بْنُ يَعْلَى بْنِ أُمَيَّةَ عَنْ أَبِيهِ قَالَ قَاتَلَ أَجِيرِي رَجُلًا فَعَضَّ يَدَهُ فَنَزَعَ يَدَهُ مِنْ فِيهِ فَأَنْدَرَ ثَنِيَّتَهُ فَأَتَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَهْدَرَهُ وَقَالَ فَيَدَعُ يَدَهُ فِي فِيكَ تَقْضِمُهَا كَمَا يَقْضِمُ الْفَحْلُ.
English Translation
Yahya ibn Sa'id told us, from Ibn Jurayj, he said: Ata' informed me, he said: Safwan ibn Ya'la ibn Umayyah informed me, from his father, who said: My hired worker fought a man and bit his hand. He pulled his hand from the man's mouth, knocking out his front tooth. He came to the Prophet, peace and blessings be upon him, who declared it void, and said, "Should he leave his hand in your mouth for you to gnaw on it as a stallion gnaws?"
