Keep in mind that "Allah" is the Arabic word for "God". Arabic Christians and Jews also use that word to refer to the God of Creation.
Yes, but “God” or “god” can mean just about anything. The key is “Jesus Christ” and unless or until they are converted, the will NEVER say or shout “Jesus”.
Islam, the Qur’an, and Sharia law are run by the spirit of antichrist - Satan’s spirit.
They are waiting for the “12th Imam” to come who will be the “beast”, Satan himself, ascending out of the bottomless pit (Rev. 11:7).
