﴿ ۞ وَلَوْ بَسَطَ ٱللَّهُ ٱلرِّزْقَ لِعِبَادِهِۦ لَبَغَوْا۟ فِى ٱلْأَرْضِ وَلَٰكِن يُنَزِّلُ بِقَدَرٍۢ مَّا يَشَآءُ ۚ إِنَّهُۥ بِعِبَادِهِۦ خَبِيرٌۢ بَصِيرٌۭ ﴾

“For, if God were to grant [in this world] abundant sustenance to [all of] His servants, they would behave on earth with wanton insolence: but as it is, He bestows [His grace] from on high in due measure, as He wills: for, verily, He is fully aware of [the needs of] His creatures, and sees them all.”

Human life on earth depends on water, but the supply of water is completely in God’s hands. If God does not provide water, man cannot obtain it on his own. Similarly, the distribution of sustenance is at the will of God. While doing so, God takes into account the depth of the human soul and, according to this, allocates sustenance to everybody. If people are given greater abundance than they can deal with with equanimity, they will become obstreperous and arrogant and, as a result, oppression and disturbance will prevail everywhere on the earth.
