﴿ إِنَّ رَبَّكَ يَبْسُطُ ٱلرِّزْقَ لِمَن يَشَآءُ وَيَقْدِرُ ۚ إِنَّهُۥ كَانَ بِعِبَادِهِۦ خَبِيرًۢا بَصِيرًۭا ﴾

“Behold, thy Sustainer grants abundant sustenance, or gives it in scant measure, unto whomever He wills: verily, fully aware is He of [the needs of] His creatures, and sees them all.”

(Lo! thy Lord) O Muhammad (enlargeth the provision) He enlarges wealth (for whom He will) of His servants as an act of consideration towards them, (and straiteneth (it for whom He will)) and He makes His provision straitened for some of His servants out of consideration for them. (Lo, He was ever Knower, Seer) of the enlarging and straitening (of His slaves) regarding that which is good for His servants.
