Abut Tufail said ‘Ali was asked whether Allah's Messenger ﷺ 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, “Allah curse him who kills an animal mentioning anyone other than Allah, and Allah curse him who steals a landmark!” A version has, “who changes a landmark; Allah curse him who curses his father; and Allah curse him who protects an innovator!” *i.e. the members of the Prophet's family. Muslim transmitted it.
