Anas b. Malik reported that Allah's Messenger (ﷺ) thus told him:
When a non-believer does good he is made to taste Its reward in this world. And so far as the believer is concerned, Allah stores (the reward) of his virtues for the Hereafter and provides him sustenance in accordance with his obedience to Him.
