Monotheism, belief in one God, is the most important and foundational concept in Islam. Muslims believe in one God who created the universe and has power over everything within it. He is unique and exalted above everything He creates, and His greatness cannot be compared to His creation. Furthermore, He is the only one deserving of any worship and the ultimate purpose of all creation is to submit to Him. The Islamic understanding of God is distinct from all other religions and beliefs in various respects since it is based on a pure and clear understanding of monotheism. This essentially captures the concept of God in Islam, which will be further elaborated.
Muslims often refer to God as Allah. This is a universal name for God and does not refer to an exclusively ‘Islamic’ god. Interestingly, this name is related to the Aramaic and Hebrew names for God, Allaha and Elohim. Therefore, Allah is simply the Arabic name for God which affirms that He is one singular god with no partners or equals. The name Allah cannot be pluralized or limited to a specific gender, which establishes that God is One and that He is unique from everything He creates. Muslims continue to use this original Arabic name for God (Allah) since it perfectly expresses His unique qualities.
