Muslims believe in all prophets from Adam to Muhammad. Major prophets include: Ibrahim (Abraham), Musa (Moses), Dawud (David), Isa (Jesus), and Muhammad – the final prophet (Seal of the Prophets).

Each prophet brought the same core message: worship one God alone. Earlier scriptures (Torah, Psalms, Gospel) became corrupted; the Quran is the final, preserved revelation.

Muslims respect all prophets equally – insulting any prophet is forbidden. However, Muhammad receives special honor as the final messenger whose example (Sunnah) Muslims follow in detail.
