My purpose here is to clarify the meaning of the terminology "Allah" which term designated by the Muslims to mean "God." In the Philippines we traditionally called the "Almighty God" as "Bathala" a term originated from a Malayo-Polynesian word "bathara" which means "god." The Malayo-Polynesian language has a history of influence with the Muslim migrants, thus the terms "bathara" (Malayo-Polynesian), "bathala" (Filipino), and "allah" (Muslim) are referred to one and the same meaning - god.
In Koran, "Allah" is the term addressed to God and "not" the name of God. According to them God has no name because He is the highest and His name must not be blasphemed. Muhammed therefore just designated the word "Allah" to address the Muslim god because he never recognized Jehovah or Yahweh as the traditionally accepted name of God. However, Muhammed himself doesn't know the name of his God.
