Amash reported,

With this chain of narration, a similar report was transmitted, except that it does not mention "on the Day of Resurrection," and it adds, "The protection granted by the Muslims is one, extended even by the lowest of them. Whoever violates the protection given by a Muslim, upon him is the curse of Allah, the angels, and all mankind. No compensation or substitute will be accepted from him on the Day of Resurrection."

Muslim 3331
