Intellectual and logical reasons that prove Tawhid [monotheism]
Tawhid [monotheism] means to believe there is only one god, it is the opposite of polytheism (shirk). Tawhid also includes denying any parallel, resembling being or any sort of imaginative or physical composition for God.
Arguments in Favor of Tawhid Dhati:
1. God has no parts and no needs. He is absolute existence and, due to his absoluteness, nothing limits His existence. If there was another wajib, each one would possess different existences and lack the existence of the other
2. If there were two powers in the world, there would be evident chaos and disorder in the world. Therefore, the fact there is order in this world shows that there is only one god.
3. If there was more than one god, the other gods would also send prophets to guide people, but such a thing has never taken place.
