LMAO! First and foremost, Muhammad did not write the Quran, nor did it exist in his time. Second of all, a good amount of the customs practiced in Mohammedianism\Islam predate the coming of Muhammad such as the hajj and the sacred shrine at the Kabba. Muhammad is simply the reformer of the pre-existing cultural customs (religion) of the tribes Shemites (according to the Bible) we now call Arabs. The spread of Muhammad and Mohammedianism was done by spreading the oral tradition brought by Muhammad which was eventually gathered and transcribed and compiled into the Quran.
Let me add that before men like Zayd ibn Amr held the tenets that became the foundation of Islam before Muhammad adopted them and returned from exile in Yahtrib (Medinat al Nabi aka City of the Prophet, contracted to Medina) to remove the idols from the shrine at Mecca.
It similar to claims that Moses wrote the first five books. But it is clear that "Jews" had an oral tradition called Mishnah before the Torah was compiled. Moses is said to have passed the oral tradition on to Joshua who later led the Israelites into the land they stole. There is no proof of anybook having been written during the time of Moses. We do however only find proof of the tradition being compiled when a Ptolemaic king gathers the elders 70 elders and had the oral tradition gathered and written down, which would become the Septuagint (LXX or G). It is interesting that the Ptolemaic king would have gathered 70 elders like Moses to compile the oral tradition.
I'll be back.
I've discussed this at length on here. If anything the Neanderthal fossils prove the bible is true...truer than science could ever hope to be.
