Muhammad was born in AD 570 in Mecca and died in 632 in Medina. He received revelations from God (Allah) starting at age 40 that became the Quran. The Quran and hadiths (accounts of Muhammad's life) form the basis of Islamic law and theology. Some passages in the Quran call for violence against non-believers, including slaying them or waging war until religion is only for Allah. In contrast, Christianity teaches that Jesus is the Son of God and the only way to salvation through faith, repentance, baptism and remaining faithful until death.
