Ali (RA) was asked: Did the Messenger of Allah single you out for something? He said: The Messenger of Allah did not single us out for anything that was not known to all people except what is in my scabbard of my sword. So, he took out a scroll on which was written: May Allah curses whoever sacrifices animals to other than Allah. Allah curses whoever steals the boundary stone of a land. Allah curses whoever curses his parent, and Allah curses whoever provides a shelter to an innovator.
