Salaam and Greetings of Peace:
Abdullah Ibn Mas`ud (may Allah be pleased with him) reported that the Prophet (peace and blessings be upon him) said, “(Believing in) bad omens is (a form of) idolatry.” Ibn Mas`ud added, “It may occur to anyone of us, but God clears it away when we rely totally on Him.” (Al-Bukhari, At-Tirmidhi, and Abu Dawud).
The same may be said of supposedly good omens. All belief in the good or bad luck of a day or an object is a belief in other than what God has provided for you.
May God bless us all with trust only in Him on this Friday the 13th.
