وَلَمَّا جَآءَ مُوسَىٰ لِمِيقَٰتِنَا وَكَلَّمَهُۥ رَبُّهُۥ قَالَ رَبِّ أَرِنِيٓ أَنظُرۡ إِلَيۡكَۚ قَالَ لَن تَرَىٰنِي وَلَٰكِنِ ٱنظُرۡ إِلَى ٱلۡجَبَلِ فَإِنِ ٱسۡتَقَرَّ مَكَانَهُۥ فَسَوۡفَ تَرَىٰنِيۚ فَلَمَّا تَجَلَّىٰ رَبُّهُۥ لِلۡجَبَلِ جَعَلَهُۥ دَكّٗا وَخَرَّ مُوسَىٰ صَعِقٗاۚ فَلَمَّآ أَفَاقَ قَالَ سُبۡحَٰنَكَ تُبۡتُ إِلَيۡكَ وَأَنَا۠ أَوَّلُ ٱلۡمُؤۡمِنِينَ

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."
