Modern Egyptologists and historians also call for caution about the credibility of the Arabian stories. They point out that medieval Arabs were guided by the strict Islamic belief that only one god exists, and therefore no other gods were allowed to be mentioned. As a consequence, they transferred Egyptian kings and gods into biblical prophets and kings. The Egyptian god Thoth, named "Hermes" by the Greeks, for example, was named after the prophet Henoch. King Khufu, as already mentioned, was named "Saurid", "Salhuk" and/or "Sarjak", and often replaced in other stories by a prophet named "Šaddād bīn 'Âd". Furthermore, scholars point to several contradictions which can be found in Al-Maqrizi's book. For example, in the first chapter of the Hitat, the Copts are said to have denied any intrusion of the Amalekites in Egypt and the pyramids were erected as the tomb of Šaddād bīn 'Âd. But some chapters later, Al-Maqrizi claims that the Copts call Saurid the builder of the pyramids.
