When Pharaoh had heard of the prophecy of Moses, peace be upon him, he sent for him and he came with his brother Aaron. Pharaoh asked about God in denying way. Then Moses started discussion about God of the whole worlds; Allah Who had created all the creatures, each one with suitable different details and Allah guided them how to live and adapt. The dialogue is mentioned in Surat Taha (49) [Pharaoh] said, "So who is the Lord of you two, O Moses?" (50) He said, "Our Lord is He who gave each thing its form and then guided [it]." The style of Moses and his brother Aaron was characterized by persuasion, unlike Pharaoh’s style of arrogance, denial, condescension, and denial. So when he couldn’t face and give a reply on Moses evidence of existence of God, pharaoh evaded and asked about the former generation. How did they reach this situation, when they preceded them in denial, disbelief, injustice, and stubbornness, and we have an example in them? Again, Moses answered steadily, their knowledge and deeds are with God and saved in a record; with God Who has no mistakes nor forget. (51) [Pharaoh] said, "Then what is the case of the former generations?" (52) [Moses] said, "The knowledge thereof is with my Lord in a record. My Lord neither errs nor forgets."
Then he continued with this conclusive evidence, mentioning many of Allah necessary blessings and benevolence. (53) [It is He] who has made for you the earth as a bed [spread out] and inserted therein for you roadways and sent down from the sky, rain and produced thereby categories of various plants. (54) Eat [therefrom] and pasture your livestock. Indeed in that are signs for those of intelligence. (55) From it [i.e., the earth] We created you, and into it We will return you, and from it We will extract you another time. And the expectant result was that Pharaoh insisted on disbelieving and denial of both existence of God and prophecy of Musa.
In contrast, that discussion has a main gain. When Asya the wife of Pharaoh watched Moses miracles and listened to their eloquent speech, she did believe in Allah and denied Pharoah as a God. She left the place where there was luxury, wealth, and servants. She endured the torment of Pharaoh and his people and called Allah to build a home for her in Paradise instead of her home with Pharoah. And she called God to survive her from Pharaoh and his people. Then she died without pain to get permanent relax.
