Quran 4:40 from Surah An-Nisaa on Divine Marvels.
إِنَّ ٱللَّهَ لَا يَظۡلِمُ مِثۡقَالَ ذَرَّةٖۖ وَإِن تَكُ حَسَنَةٗ يُضَٰعِفۡهَا وَيُؤۡتِ مِن لَّدُنۡهُ أَجۡرًا عَظِيمٗا
English translation: Indeed Allah (does) not wrong (as much as) weight (of) an atom And if there is a good He doubles it and gives from near Him a reward great
Transliteration: inna al-laha la yazlimu mith'qala dharratin wa-in taku hasanatan yuda'if'ha wayu'ti min ladun'hu ajran aziman
