سورة Al-A'raf (The Heights ) - الآية 143

And when Moosa presented himself upon Our promise, and his Lord spoke to him, he said, “My Lord! Show me Your Self, so that I may see You”; He said, “You will never be able to see Me, but look towards the mountain – if it stays in its place, then you shall soon see Me”; so when his Lord directed His light on the mountain, He blew it into bits and Moosa fell down unconscious; then upon regaining consciousness he said, “Purity is to You! I incline towards You, and I am the first Muslim.”
