It was
narrated that Rafi’ bin Khadij said:
“We were with the Prophet
(ﷺ) on a journey, and I said: ‘O Messenger of Allah, we are
(sometimes) on military campaigns, and we have no knife with us.’
He
said: ‘(Use) whatever causes the blood to flow, mention the Name
of
Allah and eat, but (do not use) teeth or nails, for the tooth is a
bone and the nail is the knife of the Ethiopians.”
