Why do muslims consider muhammad to be a prophet

For an overview of all perspectives, see Muhammad.

Muḥammad ibn ʿAbdullāh ibn ʿAbdul-Muṭṭalib ibn Hāshim (Arabic: مُحَمَّد ابْن عَبْد الله ابْن عَبْد الْمُطَّلِب ابْن هَاشِم‎) (c. 570 CE – 8 June 632 CE), in short form Muhammad, is the last Messenger and Prophet of God in all the main branches of Islam. Muslims also believe that the Quran, which is the central religious text of Islam, was revealed to Muhammad by God, and that Muhammad was sent to restore Islam, which they believe to be the unaltered original monotheistic faith of Adam, Ibrahim, Musa, 'Isa, and other Prophets.[1][2][3][4] The religious, social, and political tenets that Muhammad established with the Quran became the foundation of Islam and the Muslim world.[5]
