Al-Baqarah 2:55
وَإِذْ قُلْتُمْ يَـٰمُوسَىٰ لَن نُّؤْمِنَ لَكَ حَتَّىٰ نَرَى ٱللَّهَ جَهْرَةً فَأَخَذَتْكُمُ ٱلصَّـٰعِقَةُ وَأَنتُمْ تَنظُرُونَ
Wa-ith qultum ya moosalan nu/mina laka hatta nara Allahajahratan faakhathatkumu assaAAiqatu waantumtanthuroon
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.
When you said, “Mūsā, we will never believe you till we see Allah openly!” So, the thunderbolt took you while you were looking on.
