9. Four characteristics constitute anyone who possesses them a sheer hypocrite, and anyone who possesses one of them possesses a characteristic of hypocrisy till he abandons it: when he is trusted he betrays his trust, when he talks he lies, when he makes a covenant he acts treacherously and when he quarrels he abuses.
(Bukhari, Muslim).
(Sayings of Muhammad (pbuh). by Prof. Ghazi Ahmad).
