The Prayer of the Signs is a special form of Muslim obligatory prayer that was ordained to be said in times of natural events, like earthquakes, eclipses, and other such phenomena, which may cause fear and are taken to be signs or acts of God. The requirement of performing this prayer has been annulled. In its place a Bahá'í may say, "Dominion is God's, the Lord of the seen and the unseen, the Lord of creation," but this is not obligatory (Q and A 52).
