Signs of a hypocrite.

Narrated by Abu Hurairah that Allah's Apostle (peace be upon him) is reported to have said,"The signs of a hypocrite are three: 1.Whenever he speaks,he tells a lie 2.Whenever he promises he always breaks it (the promise) 3.If you trust him he proves to be dishonest.
(If you keep something as a trust with him,he will not return it)

[Bukhari Book1,volume 2,hadith 32]
