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 (ﷺ) 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.'
Another chain from Rafi' bin Khadij (may Allah be pleased with him) from the Prophet (ﷺ) and it is similar, but the narrator did not mention in it:
Abayah, from his father and this is more correct. 'Abayah heard from Rafi'.
