Surah 10. Yunus
Ayah 90 - 92
90 وَجَـٰوَزْنَا بِبَنِىٓ إِسْرَٰٓءِيلَ ٱلْبَحْرَ فَأَتْبَعَهُمْ فِرْعَوْنُ وَجُنُودُهُۥ بَغْيًا وَعَدْوًا ۖ حَتَّىٰٓ إِذَآ أَدْرَكَهُ ٱلْغَرَقُ قَالَ ءَامَنتُ أَنَّهُۥ لَآ إِلَـٰهَ إِلَّا ٱلَّذِىٓ ءَامَنَتْ بِهِۦ بَنُوٓا۟ إِسْرَٰٓءِيلَ وَأَنَا۠ مِنَ ٱلْمُسْلِمِينَ
91 ءَآلْـَٔـٰنَ وَقَدْ عَصَيْتَ قَبْلُ وَكُنتَ مِنَ ٱلْمُفْسِدِينَ
92 فَٱلْيَوْمَ نُنَجِّيكَ بِبَدَنِكَ لِتَكُونَ لِمَنْ خَلْفَكَ ءَايَةً ۚ وَإِنَّ كَثِيرًا مِّنَ ٱلنَّاسِ عَنْ ءَايَـٰتِنَا لَغَـٰفِلُونَ
[90-92] And We led the children of Israel across the sea. Then Pharaoh and his hosts pursued them with the intention of cruelty and oppression to them until, when he was drowning, he cried, "I have believed that there is no god but the real God in Whom the children of Israel have believed and I am of those who surrender."91 (In answer it was said : ) "Now you believe! Whereas hitherto you had been rebellious and of the mischief-makers. Now We will preserve your dead body92 only to be a sign of warning for the succeeding generations, though there are many people who give no heed to Our Signs."93
91The Bible does not mention this happening but the Talmud says explicitly that when he was drowning he said, "Who is like Thee, O Lord, among the gods?"
92Even today the place, where the dead body of Pharaoh was found floating, is pointed out by the inhabitants of that region. It lies on the western coast of the Sinai Peninsula and is now known by the name of Jabl-i-Fir`aun (Pharaoh's Mount). There is also near it a hot spring called Hammam-i-Fir`aun (Pharaoh's Bath), which is situated at a distance of a few miles from Abu Zenimah, where, they say, Pharaoh's dead body was found lying.
If the Pharaoh who was drowned was Mineptah, who ruled over Egypt when Prophet Moses was sent to him, his embalmed dead body is still lying in the Cairo Museum. When Sir Grafton E. Smith removed the bandages from his mummy, a layer of salt was found on the body, which was a clear proof that he was drowned in the sea.
93That is, "We show Signs to the people over and over again so that these should serve as warnings and be the means of teaching them lessons, but it is a pity that they do not learn lessons even from such Signs as the dead body of Pharaoh."
