The Prophet said, ''Whoever has (the following) four characters will be a hypocrite, and whoever has one of the following four characteristics will have one characteristic of hypocrisy until he gives it up. These are: (1 ) Whenever he talks, he tells a lie; (2) whenever he makes a promise, he breaks it; (3) whenever he makes a covenant he proves treacherous; (4) and whenever he quarrels, he behaves impudently in an evil insulting manner.'' (See Hadith No. 33 Vol. 1)
