أَلَمْ تَرَ أَنَّ ٱللَّهَ يُزْجِى سَحَابًا ثُمَّ يُؤَلِّفُ بَيْنَهُۥ ثُمَّ يَجْعَلُهُۥ رُكَامًا فَتَرَى ٱلْوَدْقَ يَخْرُجُ مِنْ خِلَـٰلِهِۦ وَيُنَزِّلُ مِنَ ٱلسَّمَآءِ مِن جِبَالٍ فِيهَا مِنۢ بَرَدٍ فَيُصِيبُ بِهِۦ مَن يَشَآءُ وَيَصْرِفُهُۥ عَن مَّن يَشَآءُ ۖ يَكَادُ سَنَا بَرْقِهِۦ يَذْهَبُ بِٱلْأَبْصَـٰرِ

Do you not see that God drives the clouds, then gathers them together and piles them up until you see rain pour from their midst? He sends hail down from [such] mountains in the sky, pouring it on whoever He wishes and diverting it from whoever He wishes- the flash of its lightning almost snatches sight away.
See you not that Allâh drives the clouds gently, then joins them together, then makes them into a heap of layers, and you see the rain comes forth from between them; and He sends down from the sky hail (like) mountains, (or there are in the heaven mountains of hail from where He sends down hail), and strikes therewith whom He wills, and averts it from whom He wills. The vivid flash of its (clouds) lightning nearly blinds the sight. [Tafsir At-Tabarî].
