Quran 17:100 Al-Isra, ayah 100 of 111

قُل لَّوْ أَنتُمْ تَمْلِكُونَ خَزَآئِنَ رَحْمَةِ رَبِّىٓ إِذًا لَّأَمْسَكْتُمْ خَشْيَةَ ٱلْإِنفَاقِ ۚ وَكَانَ ٱلْإِنسَـٰنُ قَتُورًا ۝١٠٠

17:100 Say (unto them): If ye possessed the treasures of the mercy of my Lord, ye would surely hold them back for fear of spending, for man was ever grudging.
