Sayyiduna Abu Hurayrah (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "Disbelief and faith cannot come together in the heart of one person, truth and lying cannot come together, and treachery and trustworthiness cannot both come together (in the heart of one person)."
Imam Ahmad recorded it; its chain contains a narrator, Ibn Lahi'ah, and he is da'if (weak).
