Al-A'raf 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

And when Mûsâ (Moses) came at the time and place appointed by Us, and his Lord (Allah) spoke to him; he said: "O my Lord! Show me (Yourself), that I may look upon You." Allâh said: "You cannot see Me, but look upon the mountain; if it stands still in its place then you shall see Me." So when his Lord appeared to the mountain¹, He made it collapse to dust, and Mûsâ (Moses) fell down unconscious. Then when he recovered his senses he said: "Glory be to You, I turn to You in repentance and I am the first of the believers."
