According to the article, it was the Quran.
-------------------------------------------
The Egyptian newspaper noted that the Quran indicates clearly "that coins were used in Egypt in the time of Joseph."
What was the Koran?
The Koran is full of crap. It wasn’t even written until 1400 AD or so, and all it contains is some Jewish bible stories that aren’t scripture, they were stories told to children.
Other stories in the Koran are twisted convoluted stories Mohammad is said to have told, but have been shown to be stories that originated in Other regions of the ME and passed along over the years.
The Koran contains nothing that is written in the bible.
