أَلَم تَرَ أَنَّ اللَّهَ يُزجي سَحابًا ثُمَّ يُؤَلِّفُ بَينَهُ ثُمَّ يَجعَلُهُ رُكامًا فَتَرَى الوَدقَ يَخرُجُ مِن خِلالِهِ وَيُنَزِّلُ مِنَ السَّماءِ مِن جِبالٍ فيها مِن بَرَدٍ فَيُصيبُ بِهِ مَن يَشاءُ وَيَصرِفُهُ عَن مَن يَشاءُ ۖ يَكادُ سَنا بَرقِهِ يَذهَبُ بِالأَبصارِ

Didn’t you see how God drives the clouds, gathers them, then stacks them up? From within their midst, you see raindrops emerge. He sends down abundant hail from the sky, striking with it whom He wills and averting it from whom He wills. The flash of its lightning almost snatches away the sight.
