I have been studying rekigions for ten years and reading bible and quran for many times. Mohammad the founder of Islam was born hundreds years after Jesus the founder of Christian and Mohammad was believed to be a merchant of leather and he would have been to many diffrents places. befor him were there main religions and he might copy and mis up thereligious beliefs of these three greatest religions. Moreover, in quran there must be found the verses of bible and it is definitely copied. Thereafter we cam fenerally say that both Christains and muslim are worshipping the same god despit of being different in points of views.
