Musnad Ahmad 32:297

Yazid narrated to us, Hammam ibn Yahya informed us, from Qatadah; and Bahz narrated to us, Hammam narrated to us, Qatadah informed us—the meaning—from Anas ibn Malik, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, Allah does not wrong a believer regarding a good deed; he is given for it in this world, and he is rewarded for it in the Hereafter. As for the disbeliever, he is fed [the reward of] his good deeds in this world, until when he reaches the Hereafter, he has no good deed for which he would be given any good."
