Musa Kalimullah (a.s.)

"La Ilaha Illallah - Musa Kalimullah."

The pharaoh who ruled Egypt was a tyrant who oppressed the descendants of Jacob , known as the children of Israel (Bani Israel). He used every means to demean and disgrace them. They were kept in bondage and forced to work for him for small wages or nothing. Under this system the people obeyed and worshipped the pharaoh, and the ruling class carried out his orders, thereby authorizing his tyranny and crazy whims.

The pharaoh wanted the people to obey him only, and to believe in the gods of his invention. Perhaps, during that time, there were many classes of people who did not believe in or practice polytheism; however, they kept this to themselves and outwardly did as they were expected to do, without revolting or revealing themselves to anyone. Thus, successive dynasties came to Egypt and assumed that they were gods or their representatives or spokesmen.
