Riyad as-Salihin — Hadith #45872

On the authority of Abu Hurairah, may God be pleased with him, that the Messenger of God, may God’s prayers and peace be upon him, said: “The signs of a hypocrite are three: when he speaks, he lies, when he makes a promise, he breaks it, and when he is trusted, he betrays” ((Agreed upon)). He added in ((A Muslim narration)): “Even if he fasts and prays and claims that he is a Muslim.”
