Surah Al-Kahf — Ayah 30 (18:30)
إِنَّ ٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّٰلِحَٰتِ إِنَّا لَا نُضِيعُ أَجۡرَ مَنۡ أَحۡسَنَ عَمَلًا ٣٠
English translation (Saheeh International)
Indeed, those who have believed and done righteous deeds - indeed, We will not allow to be lost the reward of any who did well in deeds.
Brief commentary
Those who have faith in Allah and do righteous actions have done Ill and they will receive a huge reward. I do not let the reward of those who do Ill go to waste. Instead, I give them their reward in full without any reduction.
