يَكادُ البَرقُ يَخطَفُ أَبصارَهُم ۖ كُلَّما أَضاءَ لَهُم مَشَوا فيهِ وَإِذا أَظلَمَ عَلَيهِم قاموا ۚ وَلَو شاءَ اللَّهُ لَذَهَبَ بِسَمعِهِم وَأَبصارِهِم ۚ إِنَّ اللَّهَ عَلىٰ كُلِّ شَيءٍ قَديرٌ

The lightning almost snatches away their sight. Every time it lights [the way] for them, they walk therein; but when darkness comes over them, they stand [still]. And if Allah had willed, He could have taken away their hearing and their sight. Indeed, Allah is over all things competent.
