I think he is talking about his own religion. Wasn’t his prophet an illiterate pedophile? Wasn’t his religion written down many years after the crazy child rapist died? He has a backwards culture that went into reverse when the cult became dominate in the region.
Actually, it was written while he was alive throughout his life and muslims believe that it was the word of god sent to him by archangel Gabriel. Actually the time after his death and for 500 years afterwards is referred to as the golden age, which technically had them surpassing the europeans in fields on science and technology. The decline occurred after the Mongolian invasion in the 1200s, which destroyed everything. The mongols would eventually assimilate and become the many muslim turkic people in the middle east and also gave rise to the ottoman empire.
Must be. It's the only way what he said could make sense....
