Al-Aaraf 7:143 ولما جاء موسى لميقاتنا وكلمه ربه قال رب ارني انظر اليك قال لن تراني ولاكن انظر الى الجبل فان استقر مكانه فسوف تراني فلما تجلى ربه للجبل جعله دكا وخر موسى صعقا فلما افاق قال سبحانك تبت اليك وانا اول المومنين ١٤٣

When Moses came to the place appointed by Us, and his Lord addressed him, He said: "O my Lord! show (Thyself) to me, that I may look upon thee." Allah said: "By no means canst thou see Me (direct); But look upon the mount; if it abide in its place, then shalt thou see Me." When his Lord manifested His glory on the Mount, He made it as dust. And Moses fell down in a swoon. When he recovered his senses he said: "Glory be to Thee! to Thee I turn in repentance, and I am the first to believe."
