أَخْبَرَنَا عِمْرَانُ بْنُ بَكَّارٍ، قَالَ أَنْبَأَنَا أَحْمَدُ بْنُ خَالِدٍ، قَالَ حَدَّثَنَا مُحَمَّدٌ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ، عَنْ صَفْوَانَ بْنِ عَبْدِ اللَّهِ، عَنْ عَمَّيْهِ، سَلَمَةَ وَيَعْلَى ابْنَىْ أُمَيَّةَ قَالاَ خَرَجْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي غَزْوَةِ تَبُوكَ وَمَعَنَا صَاحِبٌ لَنَا فَقَاتَلَ رَجُلاً مِنَ الْمُسْلِمِينَ فَعَضَّ الرَّجُلُ ذِرَاعَهُ فَجَذَبَهَا مِنْ فِيهِ فَطَرَحَ ثَنِيَّتَهُ فَأَتَى الرَّجُلُ النَّبِيَّ صلى الله عليه وسلم يَلْتَمِسُ الْعَقْلَ فَقَالَ " يَنْطَلِقُ أَحَدُكُمْ إِلَى أَخِيهِ فَيَعَضُّهُ كَعَضِيضِ الْفَحْلِ ثُمَّ يَأْتِي يَطْلُبُ الْعَقْلَ لاَ عَقْلَ لَهَا " . فَأَبْطَلَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم .
It was narrated from Safwan bin 'Abdullah that his two paternal uncles, Salamah and Ya'la, the sons of Umayyah, said: "We went out with the Messenger of Allah on the campaign of Tabuk, and there was a friend of ours with us, who fought with a man from among the Muslims. The man bit him on the forearm, so he pulled it away from his mouth and a tooth fell out. The man came to the Prophet, seeking blood money, but his brother and bite him like a stallion bites, then come and demand blood money? There is no blood money for that." And the Messenger of Allah juddgedit to be invalid. Translation Not Available
