Illness, food and drink

Hadith Qudsi 18:

On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Allah (mighty and sublime be He) will say on the Day of Resurrection: ‘O son of Adam, I fell ill and you visited Me not.’ He will say: ‘O Lord, and how should I visit You when You are the Lord of the worlds?’ He will say: ‘Did you not know that My servant So-and-so had fallen ill and you visited him not? Did you not know that had you visited him you would have found Me with him? O son of Adam, I asked you for food and you fed Me not.’ He will say: ‘O Lord, and how should I feed You when You are the Lord of the worlds?’ He will say: ‘Did you not know that My servant So-and-so asked you for food and you fed him not? Did you not know that had you fed him you would surely have found that (the reward for doing so) with Me? O son of Adam, I asked you to give Me to drink and you gave Me not to drink.’ He will say: ‘O Lord, how should I give You to drink when You are the Lord of the worlds?’ He will say: ‘My servant So-and-so asked you to give him to drink and you gave him not to drink. Had you given him to drink you would have surely found that with Me.’"
