SUFFERING AND THE REMOVAL OF SINS H 39 "I (Abdullah son of Mas'ud) said: 'O Messenger of Allah, praise and peace be upon him, you have a very high fever.' He replied: 'Indeed, my fever is as high as that of two of you.' I said: 'That is because you will receive twice the reward.' The Prophet, praise and peace be upon him, replied: 'That is so. A Muslim does not suffer from anything, even from a (little) thorn prick or greater, unless Allah removes (from him) in its stead some of his sins, and his sins fall as leaves fall from a tree.'" R 39 Abdullah son of Mas'ud related that he visited the Prophet, praise and peace be upon him, when he had fever and that he said this.
38- وعن ابنِ مسعودٍ رضي الله عنه ، قَالَ : دخلتُ عَلَى النَّبيِّ صلى الله عليه وآله وسلم وهو يُوعَكُ ، فقلت : يَا رسُولَ الله ، إنَّكَ تُوْعَكُ وَعْكاً شَدِيداً ، قَالَ : "أجَلْ ، إنِّي أوعَكُ كمَا يُوعَكُ رَجُلانِ مِنكُمْ" قلْتُ: ذلِكَ أن لَكَ أجْرينِ ؟ قَالَ : "أَجَلْ ، ذلِكَ كَذلِكَ ، مَا مِنْ مُسْلِمٍ يُصيبُهُ أذىً ، شَوْكَةٌ فَمَا فَوقَهَا إلاَّ كَفَّرَ اللهُ بهَا سَيِّئَاتِهِ ، وَحُطَّتْ عَنْهُ ذُنُوبُهُ كَمَا تَحُطُّ الشَّجَرَةُ وَرَقَهَا" مُتَّفَقٌ عَلَيهِ . وَ"الوَعْكُ" : مَغْثُ الحُمَّى ، وَقيلَ : الحُمَّى .
