Quran Al-Isra 17:100

قُل لَّوۡ أَنتُمۡ تَمۡلِكُونَ خَزَآئِنَ رَحۡمَةِ رَبِّيٓ إِذٗا لَّأَمۡسَكۡتُمۡ خَشۡيَةَ ٱلۡإِنفَاقِۚ وَكَانَ ٱلۡإِنسَٰنُ قَتُورٗا

Translation

Say [to them], "If you possessed the depositories of the mercy of my Lord, then you would withhold out of fear of spending." And ever has man been stingy.
