Quran 21:47 from Surah Al-Anbiyaa on Divine Marvels.
وَنَضَعُ ٱلۡمَوَٰزِينَ ٱلۡقِسۡطَ لِيَوۡمِ ٱلۡقِيَٰمَةِ فَلَا تُظۡلَمُ نَفۡسٞ شَيۡـٔٗاۖ وَإِن كَانَ مِثۡقَالَ حَبَّةٖ مِّنۡ خَرۡدَلٍ أَتَيۡنَا بِهَاۗ وَكَفَىٰ بِنَا حَٰسِبِينَ
English translation: And We set the scales (of) the justice for (the) Day (of) the Resurrection so not will be wronged any soul (in) anything And if (there) be weight (of) a seed of a mustard We will bring [with] it And sufficient (are) We (as) Reckoners
Transliteration: wanada'u al-mawazina al-qis'ta liyawmi al-qiyamati fala tuz'lamu nafsun shayan wa-in kana mith'qala habbatin min khardalin atayna biha wakafa bina hasibina
