In Islam there is only one God and there are 99 names of that one God (' lit. meaning: "The best names"), each of which evokes a distinct attribute of God. All these names refer to God, the supreme and all-comprehensive. Among the 99 names of God, the most familiar and frequent are "the Entirely Merciful" (') and "the Especially Merciful" (""). Creation and ordering of the universe is seen as an act of prime mercy for which all creatures praise God's attributes and bear witness to God's unity.
