Quran 2:20 – Second Tamtheel
Is it that these people are in far misguidance and are wandering in the desert. They are not completely doomed like the people in the previous example who were made deaf dumb and blind- they still have a chance. So when the Quran comes they walk and are guided a bit. But when it leaves they go back to their old ways? This would make sense that these people, when they hear the Quran, they have a bit of direction and take some benefit from it. Though when the little benefit they get from finding direction from lightning is not that significant since they are still stuck in their misguided deviance in the desert rain
