It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) say: "There is nothing in bad omens; the best of it is optimism." The Companions asked: What is optimism? He (peace and blessings of Allah be upon him) said: "A good word that any one of you hears."
