عَن أبي هُرَيرَة رَضِيَ اللهُ عَنهُ قَالَ قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَليهِ وَسَلَّمَ : إِنَّ اللهَ عَزَّ وَجَلَّ يَقُولُ يَومَ القِيَامَةِ يَا ابْنَ آدَمَ مَرِضْتُ فَلَمْ تَعُدْنِي قَال يَا رَبِّ كَيفَ أَعُودُكَ وَأَنْتَ رَبُّ العَالَمِينَ قَالَ أَمَا عَلِمْتَ أَنَّ عَبْدِي فُلاَنًا مَرِضَ فَلَم تَعُدْهُ أَمَا عَلِمْتَ أَنَّكَ لَو عُدتَّهُ لَوَجَدتَّنِي عِنْدَهُ. (مسلم 2/318)
Hadhrat Abu Hurayrah (Radhiallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) said: “On the day of Qiyaamah, Allah Ta’ala will say, ‘O son of Aadam (Alaihis Salaam), I fell ill but you did not visit Me.’ The person will reply, ‘O Allah, how can I visit You when you are the Lord of the worlds.’ Allah Ta’ala will reply, ‘Don’t you know that My so and so slave had fallen ill and you did not visit him? Don’t you know that had you visited him you would have surely found Me present?’
