Abu Hurayrah said that he did not like any illness more than fever because it went into each of his limbs. And, Allah grants each limb its share of reward.
Abu Hurayrah said that fever presented itself before the Holy Prophet (ﷺ). It said to him, ’’Send me to those people with whom you have a very deep connection. The Prophet (ﷺ) sent it to the Ansar. So, fever gripped them for six days and six nights. Their feverish condition became very serious and the Prophet visited them at their homes. Thy complained of fever and the Holy Prophet (ﷺ) went to each house and prayed for their health. When he was returning, one of their women followed behind him and said, "By Him who has sent you with the truth, I am of the Ansar and my father is also one of the Ansar. Just as you have prayed for the Ansar, pray for me too." The Prophet sg asked her, "What is it that you wish? If you wish, I will pray to Allah that he grant you health but if you are patient then paradise is for you." She said, "I will endure (fever) patiently and will not risk (my chance of) admission to paradise."
It is reported by Abu wail that someone said to Abu Nuhaylah (when he was ill), "Pray to Allah." So, he made this supplication, "Oh Allah, lessen the illness but do not diminish the reward." He was again asked to supplicate Allah and he said, "O Allah, let me be among the near ones and make my mother among the hoor (maids of Paradise)”.
حَدَّثَنَا عَارِمٌ، قَالَ: حَدَّثَنَا سَعِيدُ بْنُ زَيْدٍ، قَالَ: حَدَّثَنَا سِنَانٌ أَبُو رَبِيعَةَ، قَالَ: حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: مَا مِنْ مُسْلِمٍ ابْتَلاَهُ اللَّهُ فِي جَسَدِهِ إِلاَّ كُتِبَ لَهُ مَا كَانَ يَعْمَلُ فِي صِحَّتِهِ، مَا كَانَ مَرِيضًا، فَإِنْ عَافَاهُ، أُرَاهُ قَالَ: عَسَلَهُ، وَإِنْ قَبَضَهُ غَفَرَ لَهُ.
حدثنا موسى قال: حدثنا حماد بن سلمة، عن ينام عن أني، عن النبي ﷺ مثله وزاد (قال: فإن شفاه عسله).
Anas bin Maalik has reported that the Prophet (ﷺ) said, "When Allah involves a Muslim in bodily [pain then he is credited with a reward for those deeds which he was used to do when he was healthy as long as he is ill. Thus, if Allah gives him healing, He washes him (clean of sins). But, if he causes him to die then he forgives him.
