Surah Ash-Shu'ara, Ayah 44

Between Musa, peace be upon him, and the Sorcerers Allah describes the actual encounter between Musa, peace be upon him,and the Egyptians in Surat Al-A` raf, Surah Ta Ha, and in this Surah

The Egyptians wanted to extinguish the Light of Allah with their words, but Allah insisted that His Light should prevail even though the disbelievers disliked that. This is the issue of disbelief and faith; they never confront one another but faith always prevails:

بَلْ نَقْذِفُ بِالْحَقِّ عَلَى الْبَـطِلِ فَيَدْمَغُهُ فَإِذَا هُوَ زَاهِقٌ وَلَكُمُ الْوَيْلُ مِمَّا تَصِفُونَ

(Nay, We fling the truth against the falsehood, so it destroys it, and behold, it disappears. And woe to you for that which you ascribe.) (21:18)

وَقُلْ جَآءَ الْحَقُّ وَزَهَقَ الْبَـطِلُ

(And say: "Truth has come and falsehood has vanished.") (17:81) The sorcerers of Egypt were the most skilled in the art of illusion, but when a huge group of them gathered from all corners of the land, and the people came together on that day whose exact numbers are known to Allah Alone, one of them said:

بِعِزَّةِ فِرْ‌عَوْنَ (By the majesty of the Pharaoh - 26:44). This was an expression of pledge from the magicians, which was in vogue in the olden times. It is unfortunate that similar oaths have now become common among the Muslims as well, which are even more evil and vile, for instance, 'by the king,' 'by the head of yours,' 'by the beard of yours,' 'by the grave of your father' etc. It is not permitted to make an oath of this nature under the Islamic law (because swearing in the name of someone other than Allah is a sin). Rather, it will not be wrong to say that swearing a true oath in this way is as much sinful as swearing a false oath in the name of Allah. (Ruh)

Pharaoh and his courtiers considered Moses’s feats as magical in nature. So, they planned to counter them by magic. Their imagination took them no further than thinking that if Moses could change a rod into a snake, their magicians could also change sticks into snakes. They had no knowledge beyond that. They considered Moses’s actions as those of a human being and that is why they wanted to counter them by human means. They did not know the secret that Moses’s mission was a divine mission, and which human being can clash with God? The annual national festival day of the Egyptians was appointed the day for the competition between Moses and the magicians. And for this purpose, a big open area was chosen so that a large number of people could gather and give as much encouragement to the magicians as possible.
