Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said:

إِنَّ اللَّهَ عَزَّ وَجَلَّ يَقُولُ يَوْمَ الْقِيَامَةِ يَا ابْنَ آدَمَ مَرِضْتُ فَلَمْ تَعُدْنِي قَالَ يَا رَبِّ كَيْفَ أَعُودُكَ وَأَنْتَ رَبُّ الْعَالَمِينَ قَالَ أَمَا عَلِمْتَ أَنَّ عَبْدِي فُلَانًا مَرِضَ فَلَمْ تَعُدْهُ أَمَا عَلِمْتَ أَنَّكَ لَوْ عُدْتَهُ لَوَجَدْتَنِي عِنْدَهُ يَا ابْنَ آدَمَ اسْتَطْعَمْتُكَ فَلَمْ تُطْعِمْنِي قَالَ يَا رَبِّ وَكَيْفَ أُطْعِمُكَ وَأَنْتَ رَبُّ الْعَالَمِينَ قَالَ أَمَا عَلِمْتَ أَنَّهُ اسْتَطْعَمَكَ عَبْدِي فُلَانٌ فَلَمْ تُطْعِمْهُ أَمَا عَلِمْتَ أَنَّكَ لَوْ أَطْعَمْتَهُ لَوَجَدْتَ ذَلِكَ عِنْدِي يَا ابْنَ آدَمَ اسْتَسْقَيْتُكَ فَلَمْ تَسْقِنِي قَالَ يَا رَبِّ كَيْفَ أَسْقِيكَ وَأَنْتَ رَبُّ الْعَالَمِينَ قَالَ اسْتَسْقَاكَ عَبْدِي فُلَانٌ فَلَمْ تَسْقِهِ أَمَا إِنَّكَ لَوْ سَقَيْتَهُ وَجَدْتَ ذَلِكَ عِنْدِي

Allah the Exalted will say on the Day of Resurrection:

O son of Adam, I was sick but you did not visit me. He will say: O my Lord, how can I visit you when you are the Lord of the worlds? Allah will say: Did you not know that my servant was sick and you did not visit him, and had you visited him you would have found me with him?

O son of Adam, I asked you for food but you did not feed me. He will say: My Lord, how can I feed you when you are the Lord of the worlds? Allah will say: Did you not know that my servant asked you for food but you did not feed him, and had you fed him you would have found me with him?

O son of Adam, I asked you for drink but you did not provide for me. He will say: My Lord, how can I give you drink when you are the Lord of the worlds? Allah will say: My servant asked you for a drink but you did not provide for him, and had you given it to him you would have found me with him.
