Hypocrisy

Translation of Sahih Bukhari, Book 43:
Volume 3, Book 43, Number 639:

Narrated 'Abdullah bin 'Amr:

The Prophet(P.B.U.H) 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."
