I believe Islam is the origin point of all monotheism or do you disagree?
I mean I guess... but even pagan religions tend to have monotheistic elements... there's usually a king "god" or father "god".... by this logic... we could say Hindutva is based on Islam as we would could say Hinduism is based on Islam... by this logic we could say the Zionist state is based on Islam.... heck, Communism was largely influenced by Islam.... the Aztecs recognized Tezcatlipoca as their "king deity"... I guess we'd be able to say the Soviet Union, North Korea, the Spanish state that genocided Spain's Muslims, the Zionist state, the theoretical Hindu Rashtra of Hindu nationalism and the Aztec state are all based on Islam...
also- all humans are born upon the fitrah which is based on Islam.... and AI and robots and all technology are all designed by humans.... and the rocks and trees and nature were all made by Allah.... so I guess we might as well just say everything is "based on Islam".....
the Rocky movies, Pokemon, Coca-cola, voodoo, pre-Islamic Arab paganism, I guess we could just start saying everything is based on Islam....
even if we said "Omar del Sur, how dare you assert pagan religions had monotheistic elements! those filthy mushriks!"....
okay..... so if you stand outside a Baptist Church in Tennessee- you would say the Baptist Church in Tennessee is "based on Islam"? this is just a weird form of kalaam
