In Muslim belief, every prophet preached the same main Islamic beliefs, the Oneness of God, worshipping of that one God, avoidance of idolatry and sin, and the belief in the Day of Resurrection or the Day of Judgement and life after death.
Prophets in Islam (Arabic: الأنبياء في الإسلام) include "messengers" (rasul, pl. rusul), bringers of a divine revelation via an angel;12 and "prophets" (nabī, pl. anbiyāʼ), lawbringers that Muslims believe were sent by God to every people, bringing God's message in a language they can understand.13 Belief in prophets is one of the six articles of the Islamic faith, and specifically mentioned in the Quran.4
In Islamic belief the first prophet was the first human being, Adam (Adem). Many Jewish and Christian prophets and revelations they delivered are mentioned in the Quran as prophets and revelations but usually with different names, (the Jewish Elisha is called Alyasa, Job is Ayyub, Jesus is Isa, etc.; The Torah given to Moses (Musa) is called Tawrat, the Psalms given to David (Dawud) is the Zabur, the Gospel given to Jesus is Injil).
Unique to Islam is Muhammad (Muḥammad ibn ʿAbdullāh), who Muslims believe is the "Seal of the Prophets" (Khatam an-Nabiyyin, i.e. the last prophet); and the text revealed to him (the Quran), which Muslims believe is unique among divine revelations as the only one protected by God from distortion or corruption,5 destined to remain in its true form until the Last Day.
In Muslim belief, every prophet preached the same main Islamic beliefs, the Oneness of God, worshipping of that one God, avoidance of idolatry and sin, and the belief in the Day of Resurrection or the Day of Judgement and life after death. Each came to preach Islam at different times in history and some told of the coming of the final prophet and messenger of God, who would be named "Ahmed" commonly known as Muhammad. Each prophet directed a message to a different group of people, and thus would preach Islam in accordance with the times.
