Prophet Musa went to Firaun and told him that he was the messenger of Allah and he had proof. He threw his stick on the ground and it instantly turned into a serpent. Firaun demanded another miracle. He showed him the glowing arm. These miracles frightened Firaun and he turned to his advisers. They told him it was a simple trick that any good magician could perform.   So Firaun called his own magicians to the court.
