It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Allah Almighty does not wrong a believer even in regard to a single good deed; rather, the believer is rewarded for his good deeds in this world as well, and he is also given reward in the Hereafter. As for the disbeliever, Allah Almighty repays him for his good deeds in this world itself, so that when he reaches the Hereafter, there remains no good deed for which he may be rewarded.
