10:92
فَٱلْيَوْمَ نُنَجِّيكَ بِبَدَنِكَ لِتَكُونَ لِمَنْ خَلْفَكَ ءَايَةًۭ ۚ وَإِنَّ كَثِيرًۭا مِّنَ ٱلنَّاسِ عَنْ ءَايَٰتِنَا لَغَٰفِلُونَ
So today We will save you in body that you may be to those who succeed you a sign. And indeed, many among the people, of Our signs, are heedless

Tafsir
Ibn Kathīr (abridged)
The Children of Israel were saved and Fir`awn's People drowned
Allah tells us how He caused Fir`awn and his soldiers to drown. The Children of Israel left Egypt in the company of Musa. It was said that there were six hundred thousand soldiers, plus offspring. They borrowed a lot of ornaments from the Coptics and took that with them. Fir`awn became very angry with them. So he sent heralds to all the cities to send their soldiers. He embarked, following behind them, filled with great pride and with massive armies. Allah wanted this to happen for He had a plan for them. No one that had any authority or power remained behind in Fir`awn's kingdom. They were all together and caught the Children of Israel at sunrise.
فَلَمَّا تَرَآءَا الْجَمْعَانِ قَالَ أَصْحَـبُ مُوسَى إِنَّا لَمُدْرَكُونَ
(And when the two hosts met each other, the companions of Musa said: "We are sure to be overtaken.") (26:61) They said that because when they got to the seashore Fir`awn was behind them. The two groups met face to face. The people with Musa kept asking, "How can we be saved today" Musa replied, "I have been commanded to come this way." Musa said:
كَلاَّ إِنَّ مَعِىَ رَبِّى سَيَهْدِينِ
(Nay, verily, with me is my Lord. He will guide me.) (26:62) It had been so difficult, but it suddenly became easy. Allah commanded him to strike the ocean with his staff. He did and the sea was cleft asunder, each part stood like a mighty mountain. The sea was split into twelve paths, each route for each Israelite tribe. Allah then commanded the wind and the path was dry for them.
