The prophet who split the sea in Islam is Musa (Moses).
According to Islamic tradition, God commanded Musa to strike the Red Sea with his staff in order to save his followers, the Israelites, from Pharaoh and his army. By striking the sea, Musa split it into two parts, creating a path for the Israelites to escape. This event is considered a major miracle attributed to Musa in Islamic scripture.
This miraculous event is mentioned in the Quran, solidifying Musa's role as the prophet who performed this extraordinary feat. The act symbolizes divine intervention and the power of faith in the face of adversity.
