Our Muslim friends tell us that Islam is the religion of submission to Allah alone. But when we open the Qur'an, we find that Islam demands complete submission to Muhammad (Quran 4:65; 33:36). Moreover, Muhammad commanded his followers to address him directly in their prayers ("Peace be upon YOU, O Prophet"), so Muslims around the world, even in our time, speak to Muhammad in their prayers. And this is the religion that condemns other religions for idolatry?
