﴿ لَهُۥ مَقَالِيدُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ۖ يَبْسُطُ ٱلرِّزْقَ لِمَن يَشَآءُ وَيَقْدِرُ ۚ إِنَّهُۥ بِكُلِّ شَىْءٍ عَلِيمٌۭ ﴾

“His are the keys of the heavens and the earth: He grants abundant sustenance, or gives it in scant measure, unto whomever He wills: for, behold, He has full knowledge of everything.”

(His are the keys of the heavens) the stores of the heavens: rain (and the earth) vegetation. (He enlargeth providence for whom He will) He gives abundant provision to whom He will (and straiteneth (it for whom He will). Lo! He is Knower of all things) regarding expansion and straitening of provision.
