What did chalif Al-Ma'mun find inside the royal chamber in the Great Pyramid around the year of 820 of our time?

According to the Old Arabic text: "In the middle of the room there is an open (sarcophagus) bath made of polished pink granite.

In the sarcophagus lay a hollow stone statue with human features. Inside lay a man wearing a shell of gold and precious stones. His sword had incalculable value on his chest, and his face was adorned with polished rubies the size of an egg that shone brightly as daylight.

The stone statue was a mysterious inscription that no one could read. "
