Allah 30

And 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.”
