What is the evidence that the People of the Book are a people who consider carrion lawful?

Question : What is the evidence that they are a people who benefit from it?

Answer : Does this book imply that the majority of them are Christians? Yes, so what? Yes, some of them are shy about carrion. Because the Christians are very lax regarding impurities. A person prays their prayer, naturally, in the garment in which he has urinated, and he does not purify himself from the urine. The Jews are the opposite; they are strict. If a garment becomes impure with them, it is not purified except by cutting; they cut off the part that was affected by the impurity.
