The Messenger of Allah (saw) said, ’Allah, Mighty and Sublime be He, will say on the Day of Resurrection […] “O son of Adam, I asked you for food and you did not feed Me“. He will say, “O Lord, how can I feed You when You are the Lord of the worlds?” He (Allah) will say, “Did you not know that My servant so-and-so asked you for food and you did not feed him? Did you not know that had you fed him you surely would have found that (the reward for doing so) with Me?“′ [Muslim]
