hypocrite..

Our beloved Prophet Muhammad s.a.w.s. 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.

(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.”
