There's a while bundle of questions on that page, and all answered. I started to copy them out, but there were too many.
I'm guessing it's this one the one about the koran (and all abrahimic faiths) using pagan traditions, and adding some bits for political gain?
The pagan origins of most of the dates and traditions are very clear, there was a short video someone posted that showed it quite well.
The adaptations for political gain, are tied in with the reuse and adaptation of the traditions, so that people bought into it. You only need look at a few key elements to see that they're the work of a mortal, rather than a divinity. It's a common distinction made that Islam is largely a political ideology, and that is based on the writings as a good percentage of the koran and hadiths relate to dealing with fafirs and how to rule.
Its all in one post
