Read and reflect on verse 4299 from Surah Ash-Shura: 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...
۞ وَلَوْ بَسَطَ اللَّهُ الرِّزْقَ لِعِبَادِهِ لَبَغَوْا فِي الْأَرْضِ وَلَٰكِنْ يُنَزِّلُ بِقَدَرٍ مَا يَشَاءُ ۚ إِنَّهُ بِعِبَادِهِ خَبِيرٌ بَصِيرٌ
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.
