Hadith on Hypocrisy: Three signs of a hypocrite even if he says he is a Muslim

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “The signs of a hypocrite are three, even if he fasts and prays and claims to be a Muslim: when he speaks he lies, when he gives a promise he breaks it, and when he is trusted he is treacherous.”
