Ash-Shu'ara 26:63

Faawhayna ila moosaani idrib biAAasaka albahra fanfalaqafakana kullu firqin kattawdi alAAatheem

Then We inspired to Moses, "Strike with your staff the sea," and it parted, and each portion was like a great towering mountain.

So We revealed to Mūsā saying, “Strike the sea with your staff.” So it was severed apart, and each part became like a big mountain.
