There is much misunderstanding of the word Allah, especially among American Christians and much misinformation spread around. The word Allah simply means God. There are Christians in many places around the world who use the word Allah when they are praying to God. This is especially true with Arab Christians. If the Koran is being translated into English the word Allah would be translated as God because God is the English word for Allah. If the Koran is being translated into Spanish it would be Dios.
