Abut Tufail said ‘Ali was asked whether God’s messenger had given them* any instruction for themselves alone and replied that he had given them none which did not apply to all the people except what was in the scabbard of his sword. He then drew out a document containing, “God curse him who kills an animal mentioning anyone other than God, and God curse him who steals a landmark!” A version has, “who changes a landmark; God curse him who curses his father; and God curse him who protects an innovator!” *i.e. the members of the Prophet's family. Muslim transmitted it.
