("to collect") to gather magicians from various lands. At this time, magic was the trade of the day and it was widespread and popular. They had the idea that what Musa brought was a type of magic similar to the magic that the sorcerers of their time practiced. Because of this incorrect assumption, they brought all the magicians in order to defeat the miracles that he showed them. Allah said about Fir`awn,
(Then verily, we can produce magic the like thereof; so appoint a meeting between us and you, which neither we nor you shall fail to keep, in an open place where both shall have a just and equal chance." Musa said: "Your appointed meeting is the day of the festival, and let the people assemble when the sun has risen (forenoon)." So Fir`awn withdrew, devised his plot and then came back.) 20:58-60.

Ma'arif al-Qur'an

These verses narrate the remaining part of the story of the prophet Musa (علیہ السلام) . Seeing these wonders of staves turning into serpents and making his hand emitting strong white light, the Pharaoh should have been convinced and have believed in Musa (علیہ السلام) as the logic and sense demanded. But it is the common practice of the wrong-doers that they always seek false interpretations of the truth in order to conceal it, the Pharaoh and his people belied him instead, and said to the people that he was a great sorcerer and that he wanted to expel them from their homes and take over the rule of the country. The people of the Pharaoh suggested:
A prophet’s discourse is initially addressed to the leaders of the day; to those who enjoy leadership of thought in their environment. Such people, thanks to their superior intellect, are in a better position to understand the message of Truth in all its profundity. But, history shows that they have invariably always been antagonistic to the prophet’s call, i.e. they utilize their mental talents to assign a wrong meaning to the message of Truth. For example, they declare a sign which had appeared on the strength of God’s intervention to have appeared by the force of magic, or, in order to disparage the prophetic movement, give it a political colour and say that such preachers are simply seeking power. As the general public are unable to analyse matters, such talk leads them into becoming suspicious of the Truth. But to raise such frivolous points against the messenger of Truth is a great crime. In this way, the leading lights of the day may be able to preserve their leadership, but it will be at the cost of the Hereafter. God is the Truth. So it is not proper for one who comes forward in the name of God to speak of anything other than truth and justice. If he does otherwise, he will lose the right to represent God and will be liable to be punished rather than rewarded by God. Moses was sent (by God) to both the Children of Israel and to the Pharaoh and his Copt community. At that time the Children of Israel suffered from many weaknesses. However, they basically supported Moses. Unlike them, Pharaoh and his community, (with the exception of a few) rejected him. Finally, after 40 years of attempting to propagate God’s command, Moses was commanded to migrate from Egypt along with the Children of Israel. He asked Pharaoh to allow the Children of Israel to leave the country, so that they might be able to pray to the one and only God in the open atmosphere of the desert (Exodus-16). Moses was the representative of Truth, but Pharaoh considered him to be merely practising magic and decided to overcome him through his own magicians.
