Ash-Shu'ara 26:63

فَأَوْحَيْنَآ إِلَىٰ مُوسَىٰٓ أَنِ ٱضْرِب بِّعَصَاكَ ٱلْبَحْرَ ۖ فَٱنفَلَقَ فَكَانَ كُلُّ فِرْقٍ كَٱلطَّوْدِ ٱلْعَظِيمِ

Fa-awḥaynā ilā mūsā ani iḍ'rib biʿaṣāka l-baḥra fa-infalaqa fakāna kullu fir'qin kal-ṭawdi l-ʿaẓīmi

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