In Quran 10:92 it is revealed that Fir'oun will be preserved in body as a sign to those after him.
http://islamawakened.com/quran/10/92/In popular culture Pharaoh seems to be associated with Ramesses II, whose mummified remains are well preserved, seemingly consistent with what the Quran describes.
https://en.wikipedia.org/wiki/Ramesses_IIHowever I get the feeling that Ramesses II may not have been Fir'oun.
Ramesses II is described to have died at aged 90, past his physical prime and arthritic. Whereas Fir'oun appeared to be active, physically pursuing Moses until his demise (though I suppose he could have been carried or driven by horses). It just seems to me that Fir'oun was younger.
Is there anything concrete to suggest that Ramesses II was indeed the Fir'oun described in the Quran?
