7:120And the magicians fell to their knees.

7:134Whenever a plague befell them, they would say, “O Moses, pray to your Lord for us, according to the covenant He made with you. If you lift the plague from us, we will believe in you, and let the Children of Israel go with you.”

7:143And when Moses came to Our appointment, and his Lord spoke to him, he said, “My Lord, allow me to look and see You.” He said, “You will not see Me, but look at the mountain; if it stays in its place, you will see Me.” But when his Lord manifested Himself to the mountain, He turned it into dust, and Moses fell down unconscious. Then, when he recovered, he said, “Glory be to you, I repent to you, and I am the first of the believers.”
