Surah Al-Baqara Verse 55

وَإِذْ قُلْتُمْ يَا مُوسَىٰ لَن نُّؤْمِنَ لَكَ حَتَّىٰ نَرَى اللَّهَ جَهْرَةً فَأَخَذَتْكُمُ الصَّاعِقَةُ وَأَنتُمْ تَنظُرُونَ

Wa iz qultum yaa Moosaa lan nu'mina laka hattaa naral laaha jahratan fa akhazat kumus saa'iqatu wa antum tanzuroon

Translation / The Meaning

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