Quran 7:143 from Surah Al-A'raaf on Divine Marvels.
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
English translation: And when came Musa to Our appointed place and spoke to him his Lord he said O my Lord Show me (that) I may look at You He said Never you (can) see Me but look at the mountain [then] if it remains in its place then you (will) see Me But when revealed (His) Glory his Lord to the mountain He made it crumbled to dust and fell down Musa unconscious And when he recovered he said Glory be to You I turn (in repentance) to you and I am (the) first (of) the believers
