حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ حَدَّثَنَا الْأَعْمَشُ عَنْ إِبْرَاهِيمَ التَّيْمِيِّ عَنِ الْحَارِثِ بْنِ سُوَيْدٍ قَالَ قَالَ عَبْدُ اللَّهِ دَخَلْتُ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يُوعَكُ فَوَضَعْتُ يَدِي عَلَيْهِ وَقُلْتُ إِنَّكَ تُوعَكُ وَعْكًا شَدِيدًا قَالَ إِنِّي أُوعَكُ كَمَا يُوعَكُ رَجُلَانِ مِنْكُمْ قَالَ قُلْتُ ذَاكَ بِأَنَّ لَكَ أَجْرَيْنِ قَالَ أَجَلْ مَا مِنْ مُؤْمِنٍ يُصِيبُهُ مَرَضٌ فَمَا سِوَاهُ إِلَّا حَطَّ اللَّهُ بِهِ خَطَايَاهُ كَمَا تَحُطُّ الشَّجَرَةُ وَرَقَهَا
مسند امام احمد بن حنبل · Hadith 4346
It was narrated from al-Harith bin Suwaid that 'Abdullah said; I entered upon the Messenger of Allah (PBUH) and he was running a fever. I touched him with my hand and said: O Messenger of Allah, you are running a high fever. The Messenger of Allah (PBUH) said: "Yes, I am running a fever like two of you." i said: Then you will have two rewards. The Messenger of Allah (PBUH) said: "Yes. There is no Muslim who is afflicted with sickness or anything else, but Allah will erase thereby his bad deeds just as trees shed their leaves."
