﴿ ۞ وَجَٰوَزْنَا بِبَنِىٓ إِسْرَٰٓءِيلَ ٱلْبَحْرَ فَأَتْبَعَهُمْ فِرْعَوْنُ وَجُنُودُهُۥ بَغْيًۭا وَعَدْوًا ۖ حَتَّىٰٓ إِذَآ أَدْرَكَهُ ٱلْغَرَقُ قَالَ ءَامَنتُ أَنَّهُۥ لَآ إِلَٰهَ إِلَّا ٱلَّذِىٓ ءَامَنَتْ بِهِۦ بَنُوٓا۟ إِسْرَٰٓءِيلَ وَأَنَا۠ مِنَ ٱلْمُسْلِمِينَ ﴾

“And We brought the children of Israel across the sea; and thereupon Pharaoh and his hosts pursued them with vehement insolence and tyranny, until [they were overwhelmed by the waters of the sea. And] when he was about to drown, [Pharaoh] exclaimed: "I have come to believe that there is no deity save Him in whom the children of Israel believe, and I am of those who surrender themselves unto Him!"”
