THE PRESERVATION OF PHARAOH'S BODY

As we shall see later on, Pharaoh regarded himself as a deity and responded with slanders and threats to Prophet Musa's (as) calls for him to believe in Allah. This arrogant attitude lasted until he was faced with the threat of death through drowning. The Qur'an relates that Pharaoh immediately turned to belief when faced with Allah's punishment:

We brought the tribe of Israel across the sea, 

and Pharaoh and his troops pursued them out of tyranny and enmity. 

Then, when he was on the point of drowning, he [Pharaoh] said: 

"I believe that there is no god but Him in Whom the tribe of Israel believes. 

I am one of the Muslims." (Qur'an, 10:90)

However, this last-minute conversion was not accepted, for it was not sincere. According to the Qur'an, Allah exclaimed:

"What, now! When previously you rebelled and were one of the corrupters? 

Today we will preserve your body so you can be a Sign for people who come after you. 

Surely many people are heedless of Our Signs." 

(Qur'an, 10:91-92)

The information that Pharaoh's corpse would serve as a sign for later generations may be regarded as an indication that his body would not decay. On display in the Royal Mummies Chamber of the Egyptian Museum in Cairo is a mummified body believed to be that of this tyrant. In all likelihood, Pharaoh's body floated to shore after being drowned, was found and mummified by the Egyptians, and then carried to a previously prepared burial chamber.182
