Six key doctrines constitute the worldview of Islam, which are found in sura 2:177 of the Quran:
- Prophets. Allah inspires prophets to declare his message of submission to humanity. The first prophet was Adam, the first human. There are many others, including Moses, David, John the Baptist and Jesus (Qur'an 3:84), who is also known as the Messiah, sinless and a worker of wonders. About twenty-five prophets are named in the Qur'an, but Muslim tradition affirms as many as 124,000 prophets. However, the last prophet, "the seal of the prophets" (Qur'an 33:40), is Muhammad, who received God's final and perfect revelation, the Qur'an. This was received by Muhammad over about a twenty-two-year period (A.D. 610-632) and was collected and edited after his death. Another large group of writings, known as the Hadith, record events from the life of Muhammad. While these are not as authoritative as the Qur'an, they are consulted for doctrine and practice by Muslims and are thus very important for Islam.
