Islamic beliefs & theology
1.Belief in one God, Allah in Arabic, constitutes the very foundation of Islam. There is no deity except Allah. He is indivisible and absolutely transcendent. God is the Almighty, the Creator and the Sustainer of the universe, Who is similar to nothing and nothing is comparable to Him. Worship and obedience belongs to Allah and Allah alone. Joining other gods with God is an unforgivable sin. Any one who joins other gods with God has strayed far, far away from the Truth.
