Sickness Extinguishes Sins

عَنْ جَابِرُ بْنُ عَبْدِ اللَّهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَخَلَ عَلَى أُمِّ السَّائِبِ أَوْ أُمِّ الْمُسَيَّبِ فَقَالَ مَا لَكِ يَا أُمَّ السَّائِبِ أَوْ يَا أُمَّ الْمُسَيَّبِ تُزَفْزِفِينَ قَالَتْ الْحُمَّى لَا بَارَكَ اللَّهُ فِيهَا فَقَالَ لَا تَسُبِّي الْحُمَّى فَإِنَّهَا تُذْهِبُ خَطَايَا بَنِي آدَمَ كَمَا يُذْهِبُ الْكِيرُ خَبَثَ الْحَدِيدِ 

Jabir b. Abdullah reported that Allah's Messenger (ﷺ) visited Umm Sa'ib or Umm Musayyib and said: Umm Sa'ib or Umm Musayyib. Why is it that you are shivering? She said, "It is fever and may it not be blessed by Allah”, whereupon he (the Holy Prophet) said, “Don't curse fever for it expiates the sin of the children of Adam just as furnace removes the alloy of iron.”

Lessons: 

1. Health and sickness are both blessings of Allah to His beings

2. Every Muslim that is tested with any illness has to be patient and be accepting of it

3. A Muslim should not curse or lament of an illness that befalls him.

4. The test of illness, such as fever, upon the sons of Adam will rid the stain of sins as how the heat of furnace removes the rust of iron. 

May we be patient and persevere through all forms of illness.
