Az-Zumar · 39:29

29. Allah gave the example of an idolater and a monotheist as that of a man owned by disputing partners - if he pleases some he angers others and he is thus confused and disturbed; and of a man who is devoted to one man alone who owns him and whose intentions he knows - he is thus comfortable and calm. These two men are not the same. Praise be to Allah, but most of them do not know and therefore they ascribe others as partners to Allah.
