Mentioned in the fourth verse (90) was the famous miracle of Sayyidna Musa (علیہ السلام) - the crossing of the sea and the drowning of Pharaoh. There it was said:

حَتَّىٰ إِذَا أَدْرَ‌كَهُ الْغَرَ‌قُ قَالَ آمَنتُ أَنَّهُ لَا إِلَـٰهَ إِلَّا الَّذِي آمَنَتْ بِهِ بَنُو إِسْرَ‌ائِيلَ وَأَنَا مِنَ الْمُسْلِمِينَ

Until when he was about to drown, he said, "I believe that there is no god but the One in Whom the children of Isra'il believe, and I am among those who submit".
