Quote :: Abu Darda radiAllahu `anhu (may Allah be pleased with him) was one of the righteous companions of the Prophet ﷺ (peace be upon him). Once, a man came running to him saying, “O Abu Darda, your house has burned down!” He said: “No, it cannot be burned!” The man insisted that a fire had engulfed the whole neighborhood and his house was of the ones that had burned down. Abu Darda (ra) responded, with full certainty, “Allah will never allow this to happen because of the words that I heard from the Prophet ﷺ. Whoever says these words in the beginning of a day, the Prophet ﷺ told us, will not be afflicted by a misfortune until the end of the day, and whoever says these words in the evening will not be afflicted until morning.” He told him the words that he had recited that day as he had learned from the Prophet ﷺ, and when they both went to inspect the neighborhood, it turned out that most of the other houses had burned down, except the house of Abu Darda (ra).
