Four characters will be a hypocrite

The Prophet (Sallallahu 'Alaihi Wa Sallam) 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) Whenever he quarrels, he behaves impudently
in an evil insulting manner."
