Allah Taãla says in the Noble Qurãn, 'You are the best of nations sent to man. You command good and forbid evil and you believe in Allah'. (Aali Imraan).
Allah Taãla states that one reason for this Ummah being titled as the best of Ummah, is the practice of commanding good and preventing evil'.
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.”
