Muslim: Moses, David, Solomon, and Muhammad were all muslims. Me: How do you figure? Muslim: Because they all believed in one God. Me: If we are going by that definition then David, Solomon, and Muhammad were all Jewish because the Jewish Shema (a prayer within Judasim) emphasized the belief in one God 3,000 year before Muhammad/Islam existed. So, they are all Jewish. Also Hinduism is the oldest religion and they believe one a supreme being, Brahman, so everyone is Hindu by your logic.
