Hadith 6124
Sayyiduna Abu Huraira (may Allah be pleased with him) narrates, I heard the Prophet Muhammad (peace and blessings be upon him) say: "There is no reality in bad omens, and the best of them is optimism (fa’l)." It was asked, "O Messenger of Allah (peace be upon him)! What is meant by optimism (fa’l)?" The Prophet Muhammad (peace and blessings be upon him) replied: "It is a good word which a person hears."
