Surah Ash-Shura (The Consultation), Verse 27

وَلَوْ بَسَطَ اللّٰهُ الرِّزْقَ لِعِبَادِهٖ لَبَغَوْا فِی الْاَرْضِ وَلٰكِنْ یُّنَزِّلُ بِقَدَرٍ مَّا یَشَآءُ اِنَّهٗ بِعِبَادِهٖ خَبِیْرٌ بَصِیْرٌ ۟

Wa law basatal laahur rizqa li'ibaadihee labaghaw fil ardi wa laakiny yunazzilu biqadarim maa yashaaa'; innahoo bi'ibaadihee Khabeerun Baseer

“If Allah were to enlarge the provision for His Servants, they would indeed transgress beyond all bounds through the earth; but he sends (it) down in due measure as He pleases. For He is with His Servants Well-acquainted, Watchful.”

Quran 42:27 (Yusuf Ali Translation)
