Surah An-Nisaa Verse 40

إِنَّ اللَّهَ لَا يَظْلِمُ مِثْقَالَ ذَرَّةٍ ۖ وَإِن تَكُ حَسَنَةً يُضَاعِفْهَا وَيُؤْتِ مِن لَّدُنْهُ أَجْرًا عَظِيمًا

Innal laaha laa yazlimu misqaala zarratinw wa in taku hasanatany yudaa'ifhaa wa yu'ti mil ladunhu ajran 'azeemaa

Translation / The Meaning

Indeed, Allah does not do injustice, [even] as much as an atom's weight; while if there is a good deed, He multiplies it and gives from Himself a great reward.
