Introduction to history of polytheism and monotheism: Allah (glory be to him) created all people as Muslims and monotheists but devils came to them and changed and distorted their religion. Allah said in a qudsi hadith, “I created all my slaves as haneefs (monotheists), but the devils came to them, made them deviate from their religion, forbade them that which I had permitted to them, and commanded them to join partners with me for which I has given no authority.” As soon as people commit a type of polytheism, Allah sends his prophets to call them to the suitable type of monotheism.
