'Abdullah bin 'Amr:
The Prophet (ﷺ) said, "Whoever has the following four (characteristics)
will be a pure hypocrite and whoever has one of the following four
characteristics will have one characteristic of hypocrisy unless and
until he gives it up.
1. Whenever he is entrusted, he betrays.
2. Whenever he speaks, he tells a lie.
3. Whenever he makes a covenant, he proves treacherous.
4. Whenever he quarrels, he behaves in a very imprudent, evil and
insulting manner."
