According to Islamic doctrine, he was a prophet, divinely inspired to preach and confirm the monotheistic teachings of Adam, Abraham, Moses, Jesus, and other prophets.

The religion of Islam founded by Muhammad in 7th century Arabia incorporated ideas from Zoroastrianism, Judaism, and Christianity, specifically monotheism, Last Judgment, Heaven and Hell. However, it is closer to Judaism than Christianity, since it believes in the Unity of God, and God is seen as powerful rather than loving. The doctrine of Islam is based on five pillars: Shahada, faith; Salat, prayer; Zakat, alms-giving; Sawm, fasting; and Hajj, pilgrimage. Its beliefs are collected in the Quran, composed in its final form by 933. Starting from soon after its foundation, Islam has broken into several strands, including: 
Title: Muhammad in Islam
Content:  Muḥammad ibn ʿAbdullāh ibn ʿAbdul-Muṭṭalib ibn Hāshim (مُحَمَّدُ بْنُ عَبْدِ ٱللهِ بْنِ عَبْدِ ٱلْمُطَّلِبِ بْنِ هَاشِمٍ) (c. undefined570 – 8 June 632 CE), commonly known as Muhammad, is believed to be the seal of the Messengers and Prophets of God in all the main branches of Islam. Muslims believe that the Quran, the central religious text of Islam, was revealed to Muhammad by God, and that Muhammad was sent to restore Islam, which they believe did not originate with Muhammad but is the true unaltered original monotheistic faith of Adam, Abraham, Moses, Jesus, and other prophets.

Title: Women and religion
Content:  Islam is a monotheistic religion that was founded in the early seventh century by the prophet, Muhammad. The notion of a good life for a Muslim person is defined in Islam’s sacred text, the Quran, as well as the Hadith which are the direct teachings of Muhammad. Although these sources covered a lot, there were still some situations that were left to interpretation. Thus, Islamic scholars formed a consensus around a set of secondary sources, the most notable being the ijma, qiyas, ijtihad and fatwas. It is important to recognize that the Quran is not a static source with a fixed meaning 
Title: Islam
Content:  Islam (اَلْإِسْلَامُ, "submission [to God]") is an Abrahamic monotheistic religion teaching that Muhammad is a messenger of God. It is the world's second-largest religion with 1.9 billion followers, or 24.9% of the world's population, known as Muslims. Muslims make up a majority of the population in 49 countries. Islam teaches that God is merciful, all-powerful, and unique, and has guided humanity through prophets, revealed scriptures, and natural signs.

Title: Isaac in Islam
Content:  The biblical patriarch Isaac (إسحاق or إسحٰق ʾIsḥāq) is recognized as a prophet and messenger of God by Muslims. As in Judaism and Christianity, Islam maintains that Isaac was the son of the patriarch and prophet Abraham from his wife Sarah. Muslims hold Isaac in deep veneration because they believe that both Isaac and his older half-brother Ishmael continued their father's spiritual legacy through their subsequent preaching of the message of God after the death of Abraham. Isaac is mentioned in fifteen passages of the Quran. Along with being mentioned several times in the Quran, Isaac is held up as one of Islam's prophets.

They were followed by a millennium of theologians known as the Church Fathers. Islam was founded by Muhammad, and his successor Abu Bakr, Umar, Uthman ibn Affan and Ali, for Sunnis and Ali ibn Abi Talib and The Twelve Imams for those of Shia faith, were also men.

Among Isaac's children was the follow-up Israelite patriarch Jacob, who is also venerated as an Islamic prophet. Isaac is mentioned seventeen times by name in the Quran, often with his father and his son, Jacob. The Quran states that Abraham received "good tidings of Isaac, a prophet, of the righteous", and that God blessed them both (37: 112).
