وَلَو بَسَطَ اللَّهُ الرِّزقَ لِعِبادِهِ لَبَغَوا فِي الأَرضِ وَلـٰكِن يُنَزِّلُ بِقَدَرٍ ما يَشاءُ ۚ إِنَّهُ بِعِبادِهِ خَبيرٌ بَصيرٌ

If God were to expand the provision for His servants, they would commit excess on earth. But He sends down what He wills in measured amounts. He is All-Seeing and All-Aware of His beings.
