I meant, and wrote about it in another thread, that the Kaaba is not Islamic at all. Historically, it is said to be an ancient Hindu temple and actually has Hindu writing on it (if they did not remove it already). Hindu rites came into "traditional Islam" which has nothing to do with true Islaam. In the Quran, it is against Islaam to worship rocks like the "Muslims" do.
There is nothing natural about worshiping rocks, so using that definition of paganism does not apply here.
