Ja'far bin Muhammad narrates from his father, and he from his grandfather (may Allah be pleased with him), that a note was found in the scabbard of the Prophet (peace and blessings be upon him), on which was written: "The greatest rebel against Allah." In the narration of Sulayman the words are: "The most insolent is the one who kills someone other than the killer, and strikes someone other than the one who struck him; and whoever runs away from his master has disbelieved in what was revealed to Muhammad (peace and blessings be upon him)."
