The polytheists approved of monotheism
The answer is: Unity of Deism
The polytheists in Mecca agreed to the monotheism of divinity indirectly, when they accepted the laws of Islam and the rule of God, which makes the Lord of the universe the only one worthy of worship. They considered idols and other gods to be partners to God Almighty, but after they accepted Islam and learned about true monotheism, they acknowledged their belief that God He is the ruler of the universe and is the only god worthy of worship and reverence. This means that Muslims must deal with polytheists with dignity and respect if they accept Islamic monotheism with open arms.
