"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.'"
