"The Messenger of Allah said: 'Whoever kills a Mu'ahad with no justification, Allah will forbid Paradise to him."
Sunan an-Nasa'i Book 45, Hadith 42
← Previous Hadith "What the people have been hearing from you has become widespread. If the Messenger of Allah told you anything, then tell us," He said: "The Messenger of Allah did not tell me anything that he did not tell the people, except that in the sheath of my sword there is a sheet, in which it says: 'The lives of the believers are equal in value, and they hasten to support the asylum granted by the least of them. But no believer may be killed in return for a disbeliever, nor one with a covenant while his covenant is in effect."' It is an abridgement of it.
