﴿ ٱللَّهُ ٱلَّذِى يُرْسِلُ ٱلرِّيَٰحَ فَتُثِيرُ سَحَابًۭا فَيَبْسُطُهُۥ فِى ٱلسَّمَآءِ كَيْفَ يَشَآءُ وَيَجْعَلُهُۥ كِسَفًۭا فَتَرَى ٱلْوَدْقَ يَخْرُجُ مِنْ خِلَٰلِهِۦ ۖ فَإِذَآ أَصَابَ بِهِۦ مَن يَشَآءُ مِنْ عِبَادِهِۦٓ إِذَا هُمْ يَسْتَبْشِرُونَ ﴾

“It is God who sends forth the winds [of hope], so that they raise a cloud - whereupon He spreads it over the skies as He wills, and causes it to break up so that thou seest rain issue from within it: and as soon as He causes it to fall upon whomever He wills of His servants - lo! they rejoice,”

God is the One Who unleashes the winds which then raise stir up clouds and He then spreads them across the heaven as He will in small or large quantities and He forms them into fragments read kisafan or kisfan ‘scattered pieces’ then you see the rain issuing out of them that is out of the midst of them. Then when He drops it the rain upon whomever of His servants He will lo! they rejoice they are happy because of the rain.
