When Moses came at the appointed time and his Lord spoke to him, he asked, “My Lord! Reveal Yourself to me so I may see You.” Allah answered, “You cannot see Me! But look at the mountain. If it remains firm in its place, only then will you see Me.” When his Lord appeared to the mountain, He levelled it to dust and Moses collapsed unconscious. When he recovered, he cried, “Glory be to You! I turn to You in repentance and I am the first of the believers.” Quran: 7:143
