Surah Al-Anbiya Verse 47 - English Translation by N J Dawood
Surah Al-Anbiyaوَنَضَعُ ٱلۡمَوَٰزِينَ ٱلۡقِسۡطَ لِيَوۡمِ ٱلۡقِيَٰمَةِ فَلَا تُظۡلَمُ نَفۡسٞ شَيۡـٔٗاۖ وَإِن كَانَ مِثۡقَالَ حَبَّةٖ مِّنۡ خَرۡدَلٍ أَتَيۡنَا بِهَاۗ وَكَفَىٰ بِنَا حَٰسِبِينَ
We shall set up just scales for the Day of Resurrection, so that no soul shall in the least be wronged. Actions as small as a grain of mustard seed shall be weighed out. Our reckoning shall suffice
