"'Abdullah ibn 'Amr ibn al-'As reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "If anyone has four characteristics, he is a pure hypocrite, and if anyone has one of them, he has an aspect of hypocrisy until he gives it up: whenever he is trusted, he betrays his trust; whenever he speaks, he lies; whenever he makes an agreement, he breaks it; and whenever he quarrels, he deviates from the truth speaks falsely.""
