It was narrated that Abu Wa'il said:"Abdullah said: 'There are three (traits), whoever has them is a hypocrite: When he speaks, he lies; when he is entrusted with something, he betrays that trust; and when he makes a promise, he breaks it. Whoever has one of these (traits) then a trait of hypocrisy has not ceased in him, until he leaves it.'" (Sahih Mawquf)
