The Prophet (may Allah's peace and blessings be upon him) did not believe in evil omens

Explanation of the hadith

The Prophet (may Allah's peace and blessings be upon him) never took anything as a bad omen. Islam has prohibited pessimism, the kind that prevents one from doing what he intended to do as practiced in the pre-Islamic era, taking evil omens, and divination by arrows. It offered the substitute represented in the Istikhārah prayer.
