Al Anbya Ayah 47

وَنَضَعُ ٱلْمَوَٲزِينَ ٱلْقِسْطَ لِيَوْمِ ٱلْقِيَـٰمَةِ فَلَا تُظْلَمُ نَفْسٌ شَيْــًٔا‌ۖ وَإِن كَانَ مِثْقَالَ حَبَّةٍ مِّنْ خَرْدَلٍ أَتَيْنَا بِهَا‌ۗ وَكَفَىٰ بِنَا حَـٰسِبِينَ ٤٧ We will set up the scales of justice on the Day of Judgment, so no soul will be wronged in the least. And ?even? if a deed is the weight of a mustard seed, We will bring it forth. And sufficient are We as a ?vigilant? Reckoner.
