Al-Baqarah 55

وَإِذْ قُلْتُمْ يَـٰمُوسَىٰ لَن نُّؤْمِنَ لَكَ حَتَّىٰ نَرَى ٱللَّهَ جَهْرَةً فَأَخَذَتْكُمُ ٱلصَّـٰعِقَةُ وَأَنتُمْ تَنظُرُونَ

wa-idh qul'tum yāmūsā lan nu'mina laka ḥattā narā l-laha jahratan fa-akhadhatkumu l-ṣāʿiqatu wa-antum tanẓurūna

And [recall] when you said, "O Moses, we will never believe you until we see Allāh outright"; so the thunderbolt took you while you were looking on.
