Muḥammad ibn ʿAbdullāh ( 570 – 632), in short form Muhammad, is considered in Islam to be the greatest messenger (Quran ) and prophet sent by God to guide humanity to the right way (Quran ). Muslims believe that Muhammad is the final prophet sent by God; and the Quran, which is the central religious text of Islam, was revealed to Muhammad by God. According to Muslims, he was sent to restore Islam, which they believe to be the unaltered original monotheistic faith of Adam, Ibrahim, Musa, Isa, and other prophets. The religious, social, and political tenets that Muhammad established in the light of Quran became the foundation of Islam and Islamic civilization.
