Here is a highly compressed account by Dr. Bucaille of his research and study of this subject that appears in one of his books. Dr. Bucaille writes :
"I have noted the points where the Biblical and Quranic narrations agree and disagree, and, for some details, I have found points where the two texts complement each other in a very useful way. Among the many hypotheses concerning the position oc-cupied by the Exodus in the history of the Pharaohs, I have concluded that the most likely is the theory which makes Memeptah, Rameses II's successor, the Pharaoh of the Exodus. The confrontation of the data contained in the Scriptures with archaeological evidence speaks strongly in favor of this hypothesis. I am pleased to be able to say that the Biblical narration contributes weighty evidence leading us to situate Moses in the history of the Pharaohs: Moses was born during the reign of Rameses II. Biblical data are therefore of considerable historical value in the story of Moses.The medical study of the mummy of Memeptah has yielded further useful information on the possible causes of this Pharaoh's death.The fact that we today possess the mummy of this Pharaoh, which was discovered in 1898, is one of paramount importance. The Bible records that it was engulfed in the sea, but does not give any details as to what subsequently became of the body. The Quran (10:92) notes that the body of the Pharaoh, who was to be damned, would be saved from the waters. A medical examination of this mummy, has moreover, shown that the body could not have stayed in the water for long, because it does not show signs of deterioration due to prolonged submersion. Here again, the confrontation of the narration in the Quran with the data provided by modern knowledge does not give rise to the slightest objection from a scientific point of view."
The physical living SIGN of God is a preserved dead body residing in the Egyptian Museum in Cairo for every one to see, but many among mankind are unmindful of God's "SIGNS".
