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.”

7:155And Moses chose from his people seventy men for Our appointment. When the tremor shook them, he said, “My Lord, had You willed, You could have destroyed them before, and me too. Will you destroy us for what the fools among us have done? This is but Your test—with it You misguide whomever You will, and guide whomever You will. You are our Protector, so forgive us, and have mercy on us. You are the Best of Forgivers.”
