Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: There are three traits; whoever possesses them is a hypocrite, even if he fasts, prays, and thinks that he is a Muslim: when he speaks, he lies; when he makes a promise, he breaks it; and when he is entrusted, he betrays the trust.
