Muhammad (c. 570 – 8 June 632 CE) was an Arab religious, military and political leader, as well as the founder of Islam. According to Islam, he was the final prophet of God who was divinely inspired to preach and confirm the monotheistic teachings of Adam, Noah, Abraham, Moses, Jesus, and other prophets in Islam. He is believed by Muslims to be the Seal of the Prophets, and along with the Quran, his teachings and normative examples form the basis for Islamic religious belief.
