Koran is a propaganda by Muhammed(PBUH) to implement his supremacy among the Arab(PBUT) tribes.He(PBUH) claimes he(PBUH) was the chosen one and allah spoke to him(pbuh) in Arabic,while actually allah knew only Sanskrit.He(PBUH) killed,raged wars,revolted and when his position was established,suddenly became an advocate for Peace.So don't tell me it is Ramayana that is fiction.
