حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ سَعِيدِ بْنِ مَسْرُوقٍ، عَنْ عَبَايَةَ بْنِ رِفَاعَةَ بْنِ رَافِعِ بْنِ خَدِيجٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، رَافِعِ بْنِ خَدِيجٍ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّا نَلْقَى الْعَدُوَّ غَدًا وَلَيْسَتْ مَعَنَا مُدًى فَقَالَ النَّبِيُّ صلى الله عليه وسلم " مَا أَنْهَرَ الدَّمَ وَذُكِرَ اسْمُ اللَّهِ عَلَيْهِ فَكُلُوهُ مَا لَمْ يَكُنْ سِنًّا أَوْ ظُفُرًا وَسَأُحَدِّثُكُمْ عَنْ ذَلِكَ أَمَّا السِّنُّ فَعَظْمٌ وَأَمَّا الظُّفُرُ فَمُدَى الْحَبَشَةِ " .
Narrated Rafi' bin Khadij: "I said: 'O Messenger of Allah! We expect to meet the enemy tomorrow and we have no knives.' So the Prophet (PBUH) said: 'As long as it causes blood to flow, and Allah's Name has been mentioned over it, then eat it, provided that it was not done with a tooth or nail. And I will tell you why: As for the tooth it is a bone, and as for the nail it is the knife of the Ethiopians.'" Translation Not Available
