In the Qur'an, the title of the Ruler of Egypt during the time of Joseph is specifically said to be "King" (Arabic: Malik) whilst that of the Ruler of Egypt during the time of Moses is specifically said to be "Pharaoh." This is interesting because according to historical sources, the title "Pharaoh" only began to be used to refer to the rulers of Egypt (starting with the rule of Thutmose III) in 1479 BCE - approximately 21 years after the prophet Joseph died. But in the narration of Yusuf in the Bible, the titles "King" (Hebrew: Melekh) and "Pharaoh" are used interchangeably for the ruler of Egypt in Genesis chapters 39-41.
