Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: “Indeed, Allah does not wrong a believer even in regard to a single good deed. The believer is rewarded for his good deeds in this world, and he will also be rewarded in the Hereafter. As for the disbeliever, the good deeds he does for Allah are recompensed for him in this world itself. Therefore, when he meets Allah on the Day of Resurrection, he will have no good deed left for which he may be rewarded.”
