How can one convince an unbeliever, who does not believe in the Qur'an or the Sunnah, that his belief that the sky is the harmful, beneficial, heard, and seen creator god is a false belief, and what is the method for convincing one who believes in other gods besides the sky?

One can argue against those who believe the sky or other created beings are deities by demanding they prove these beings possess divine and lordly attributes, and the difference between them and other created things. If their proof is the descent of rain, then all created things have benefits and characteristics indicating they are created and subservient. Furthermore, rain, thunder, and lightning do not originate from the sky itself but from its direction, and the sky itself is created, and not the greatest of creations; there are the Throne and the Footstool. The claim that the sky hears, sees, benefits, and harms requires conclusive proof. These arguments apply to anyone who believes in a god other than Allah, but such an argument requires scholarly proficiency and deep-rooted knowledge.
