Do you not see that Allah drives clouds? Then He brings them (24:43)

﴿أَلَمْ تَرَ أَنَّ اللَّهَ يُزْجِي سَحَابًا ثُمَّ يُؤَلِّفُ بَيْنَهُ ثُمَّ يَجْعَلُهُ رُكَامًا فَتَرَى الْوَدْقَ يَخْرُجُ مِنْ خِلَالِهِ وَيُنَزِّلُ مِنَ السَّمَاءِ مِن جِبَالٍ فِيهَا مِن بَرَدٍ فَيُصِيبُ بِهِ مَن يَشَاءُ وَيَصْرِفُهُ عَن مَّن يَشَاءُ ۖ يَكَادُ سَنَا بَرْقِهِ يَذْهَبُ بِالْأَبْصَارِ﴾
[ النور: 43]

24:43 Do you not see that Allah drives clouds? Then He brings them together, then He makes them into a mass, and you see the rain emerge from within it. And He sends down from the sky, mountains [of clouds] within which is hail, and He strikes with it whom He wills and averts it from whom He wills. The flash of its lightening almost takes away the eyesight.

O Messenger! Do you not know that Allah drives the clouds, then joins parts of them together, then makes them into layers, one above the other.
You then see the rain coming out from the cloud, and falling from the sky from parts of cloud like mountains, falling as hail.
That hail reaches whoever Allah wills from His servants, and He turns it away from whomsoever He wills.
It is extremely possible that the light from bolts of lightning blinds the eyesight.

See you not that Allah 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 strike therewith whom He will, and averts it from whom He wills. The vivid flash of its (clouds) lightning nearly blinds the sight. [Tafsir At-Tabari].

Abdullah Yusuf Ali - Translation

Seest thou not that Allah makes the clouds move gently, then joins them together, then makes them into a heap? - then wilt thou see rain issue forth from their midst. And He sends down from the sky mountain masses (of clouds) wherein is hail: He strikes therewith whom He pleases and He turns it away from whom He pleases, the vivid flash of His lightning well-nigh blinds the sight.

Safi-ur-Rahman al-Mubarakpuri

See you not that Allah drives the clouds gently, then joins them together, then makes them into a heap of layers, and you see the rain come forth from between them; and He sends down from the sky, from mountains in it of ice, and strikes therewith whom He wills, and averts it from whom He wills. The vivid flash of its (clouds) lightning nearly blinds the sight.
