Faawhayna ila moosa ani idrib biAAasaka albahra fanfalaqa fakana kullu firqin kattawdi (surah Shuara: 63)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(26:63) We inspired Moses with the Command: "Smite the sea with your staff." The sea parted forthwith and its each part stood like a mighty mountain. *47

Fa awhainaaa ilaa Moosaaa anidrib bi`asaakal bahra fanfalaqa fakaana kullu firqin kattawdil `azeem

*47) Literally, tawd is a high mountain. It appears that as soon as Prophet Moses struck the sea with his staff, it tore the sea asunder and the waters stood like two mighty mountains on the sides and remained in that condition for so long that, on the one hand, the Israelite caravans consisting of hundreds of thousands of the nigrants were able to pass through safely, and on the other, Pharaoh and his hosts stepped in and reached the middle of the sea. In the natural course, a phenomenon like this has never occurred that due to a windstorm, however strong, the sea should have parted and stood like mighty mountains on either side for such a long time. According to verse 77 of Ta Ha, Prophet Moses was commanded by Allah "to make for them (the Israelites) a dry path across the sea. " This shows that the smiting of the sea did not only result in dividing the waters into two parts, which stood like mighty mountains on either side, but it also created a dry path in between without any mud or slush. In this connection, one should also consider verse 24 of Surah Dukhan, which says that after Moses had crossed the sea along with his people, he was commanded by Allah "to let the sea remain as it is because Pharaoh is to be drowned in it." This implies that if after crossing the sea, Moses had again struck it with his staff, the two sides would have rejoined, but he was forbidden to do so. Obviously, this was a miracle, and the view of those who try to interpret it as a natural phenomenon, is belied. For explanation, see E.N. 53 of Ta Ha.
