I visited Messenger of Allah ﷺ as he was running a high temperature. I touched his body with my hand and said to him: Messenger of Allah, you are running a high temperature, whereupon Messenger of Allah ﷺ said: Yes, it is so. I comparatively have a more severe fever than any one of you. I said: Is it because there is a double reward in store for you? Thereupon Messenger of Allah ﷺ said: Yes, it is so. And Messenger of Allah ﷺ again said: When a Muslim falls ill, his compensation is that his minor sins are obliterated just as leaves fall (in autumn). In the hadith transmitted on the authority of Zubair there is (no mention of these words):" I touched his body with my hands."
دَخَلْتُ عَلَى رَسُولِ اللَّهِ ﷺ وَهُوَ يُوعَكُ فَمَسِسْتُهُ بِيَدِي فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّكَ لَتُوعَكُ وَعْكًا شَدِيدًا فَقَالَ رَسُولُ اللَّهِ ﷺ أَجَلْ إِنِّي أُوعَكُ كَمَا يُوعَكُ رَجُلاَنِ مِنْكُمْ قَالَ فَقُلْتُ ذَلِكَ أَنَّ لَكَ أَجْرَيْنِ فَقَالَ رَسُولُ اللَّهِ ﷺ أَجَلْ ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ مُسْلِمٍ يُصِيبُهُ أَذًى مِنْ مَرَضٍ فَمَا سِوَاهُ إِلاَّ حَطَّ اللَّهُ بِهِ سَيِّئَاتِهِ كَمَا تَحُطُّ الشَّجَرَةُ وَرَقَهَا
