Arabic

حَدَّثَنَا مُوسَى، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُسْلِمٍ، حَدَّثَنَا سُلَيْمَانُ، عَنْ إِبْرَاهِيمَ التَّيْمِيِّ، عَنِ الْحَارِثِ بْنِ سُوَيْدٍ، عَنِ ابْنِ مَسْعُودٍ ـ رضى الله عنه ـ قَالَ دَخَلْتُ عَلَى النَّبِيِّ صلى الله عليه وسلم وَهْوَ يُوعَكُ فَمَسِسْتُهُ فَقُلْتُ إِنَّكَ لَتُوعَكُ وَعْكًا شَدِيدًا‏.‏ قَالَ ‏"‏ أَجَلْ كَمَا يُوعَكُ رَجُلاَنِ مِنْكُمْ ‏"‏‏.‏ قَالَ لَكَ أَجْرَانِ قَالَ ‏"‏ نَعَمْ مَا مِنْ مُسْلِمٍ يُصِيبُهُ أَذًى مَرَضٌ فَمَا سِوَاهُ إِلاَّ حَطَّ اللَّهُ سَيِّئَاتِهِ كَمَا تَحُطُّ الشَّجَرَةُ وَرَقَهَا ‏"‏‏.‏
