Quran

(It is He Who spread out the earth for you), like a bed. Moreover, see how Moses (u) described his Lord with attributes that Pharaoh cannot attain, neither realistically nor metaphorically. Had Moses (u) described Allah as: "the Creator", “the Sustainer”, Pharaoh would have misconstrued that and claimed the same for himself. Ibn Juzay: 2/20.
Question: The effective preacher should be convincing in his argument; how can you learn that from the dialogue between Moses (u) and Pharaoh?

(There are signs in this for people of sound intellect) to those who use reason. In the Arabic text, the word "Nuha" is used, which means a good judgment that keeps one from falling into sins and disgrace. Al-Baghawi: 3/126.
Question: Allah refers to the people who use reason as those who have (Nuha). Why?

Allah singles out people of sound intellect here because they are the ones who benefit from the signs and reflect on them. As for others, they are more akin to grazing animals, for they do not look at the signs and reflect upon them, and they do not think deeply in order to find the purpose behind them. Rather, their share is that of animals that eat and drink whilst living a life of heedlessness, and turning away from the truth. Al-Saadi: 507.
Question: Who benefits from the outcomes of Allah's blessings and His power, and recognizes their aims?

Pharaoh claimed that these signs that Moses (u) showed him were no more than magic and illusions, the purpose of which was to drive them from their land and take it over, so that his [Pharaoh's] words would have some impact on his people, for people are naturally inclined toward their homelands, and it is difficult for them to leave them. Al-Saadi: 508.
Question: Pharaoh accused Moses (u) that he came to drive him and his people from their land. Why?

Moses (u) appointed for them the day of the festival in order to raise high the word and religion of Allah and debase the disbelievers with their falsehood for all people to see in the crowded gathering, thus, strengthening the desire of those who search for the truth while weakening the falsifiers and their followers. Moreover, the news of this encounter would travel throughout the land by the spectators' talks and reach every house inside the community and outside. Al-Qurtubi: 14/86.
Question: Moses (u) appointed the day of the festival for Pharaoh and his people. Why?

The phrase "putting together" refers to planning the encounter against Moses (u), setting up the tricks to show the superiority of the magicians over him, and convincing the attending crowd that Moses (u) has nothing to show for. This is an old style of debating in which one side tries to show the falsehood of his opponent's argument, using all means to confuse, culminate, and defame him. Moreover, startling him with things that weaken his resolve and bewilder his mind until he loses control. Ibn Ashur: 16/247.
Question: The verse mentions one of Pharaoh's debating styles. What is it?

Because that is more convenient for your performance, and will create greater awe in people's hearts, and so that none of you will do less than he is able to. Al-Saadi: 508.
Question: Why did the magicians advised each other of coming forward in line?
