An Nisa, 40 Ayah
4:40
إِنَّ ٱللَّهَ لَا يَظۡلِمُ مِثۡقَالَ ذَرَّةٖۖ وَإِن تَكُ حَسَنَةٗ يُضَٰعِفۡهَا وَيُؤۡتِ مِن لَّدُنۡهُ أَجۡرًا عَظِيمٗا ٤٠
'Inna Al-Laha Lā Yažlimu Mithqāla Dharratin ۖ Wa 'In Taku Ĥasanatan Yuđā`ifhā Wa Yu'uti Min Ladunhu 'Ajrāan `Ažīmāan
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.
