The Messenger of Allah (ﷺ) sent a man of the Ansar to level every grave and spoil every idol. He said: O Messenger of Allah (ﷺ), I do not like to enter the houses of my people. So he sent me, and when I came back he said: "O ‘Ali, do not be a cause of division, or a show-off, or a merchant, except a good merchant, for they are the ones who procrastinate - or who are lagging behind - in doing good deeds."
