﴿ وَإِذْ قُلْتُمْ يَٰمُوسَىٰ لَن نُّؤْمِنَ لَكَ حَتَّىٰ نَرَى ٱللَّهَ جَهْرَةًۭ فَأَخَذَتْكُمُ ٱلصَّٰعِقَةُ وَأَنتُمْ تَنظُرُونَ ﴾

“And [remember] when you said, "O Moses. indeed we shall not believe thee unto we see God face to face!" - whereupon the thunderbolt of punishment overtook you before your very eyes.”

And when you said having gone out with Moses to apologise before God for your worship of the calf and having heard what he had said to you; ‘O Moses we will not believe you till we see God openly’ with our own eyes; and the thunderbolt the shout took you and you died while you were beholding what was happening to you.
