And when Musa came at Our appointed time and his Lord spoke to him, he said: My Lord! show me (Thyself), so that I may look upon Thee. He said: You cannot (bear to) see Me but look at the mountain, if it remains firm in its place, then will you see Me; but when his Lord manifested His glory to the mountain He made it crumble and Musa fell down in a swoon; then when he recovered, he said: Glory be to Thee, I turn to Thee, and I am the first of the believers.
