Narrated `Abdullah:
حَدَّثَنَا قَبِيصَةُ ، حَدَّثَنَا سُفْيَانُ ، عَنِ الأَعْمَشِ ، عَنْ إِبْرَاهِيمَ التَّيْمِيِّ ، عَنِ الْحَارِثِ بْنِ سُوَيْدٍ ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم فِي مَرَضِهِ فَمَسِسْتُهُ وَهْوَ يُوعَكُ وَعْكًا شَدِيدًا فَقُلْتُ إِنَّكَ لَتُوعَكُ وَعْكًا شَدِيدًا، وَذَلِكَ أَنَّ لَكَ أَجْرَيْنِ. قَالَ " أَجَلْ، وَمَا مِنْ مُسْلِمٍ يُصِيبُهُ أَذًى إِلاَّ حَاتَّتْ عَنْهُ خَطَايَاهُ كَمَا تَحَاتُّ وَرَقُ الشَّجَرِ " .
I visited the Prophet (ﷺ) during his illness and touched him while he was having a fever. I said to him, "You have a high fever; is it because you will get a double reward?" He said, "Yes. No Muslim is afflicted with any harm, but that his sins will be annulled as the leave of a tree fall down."
