The prophet who split the ocean is Moses (Musa in Islam).
Moses, revered in Judaism, Christianity, and Islam, is most famously known for the miracle where he parted the Red Sea (or Sea of Reeds) to allow his followers to escape the pursuing Egyptian army.
According to religious texts, when Moses and the Israelites were trapped between the sea and Pharaoh's approaching forces, God commanded Moses to strike the water with his staff. This act resulted in the sea dividing, creating a path for the Israelites to cross on dry land. Once they had safely crossed, the sea collapsed, engulfing the pursuing Egyptian army.
This event is a pivotal moment in the history of the Israelites and is a powerful symbol of divine intervention and deliverance.
