"The parable of the ill when he is cured and becomes healthy is that of hail that falls from the heavens in its purity and its color."  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّمَا مَثَلُ الْمَرِيضِ إِذَا بَرَأَ وَصَحَّ كَالْبَرْدَةِ تَقَعُ مِنَ السَّمَاءِ فِي صَفَائِهَا وَلَوْنِهَا  

"When one of you visits the ill, then reassure him regarding his lifespan. Indeed that will not repel anything, but it will comfort his soul."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلْتُمْ عَلَى الْمَرِيضِ فَنَفِّسُوا لَهُ فِي أَجَلِهِ فَإِنَّ ذَلِكَ لاَ يَرُدُّ شَيْئًا وَيُطَيِّبُ نَفْسَهُ  

"Cheer up, for indeed Allah said: 'It is My Fire which I impose upon My sinning slave as his portion of the Fire." (Hasan) Al-Hasan said: "They would hope that the fever that occurred at night would atone for any deficiency caused by sins."  

أَنَّ النَّبِيَّ ﷺ عَادَ رَجُلاً مِنْ وَعَكٍ كَانَ بِهِ فَقَالَ أَبْشِرْ فَإِنَّ اللَّهَ يَقُولُ هِيَ نَارِي أُسَلِّطُهَا عَلَى عَبْدِي الْمُذْنِبِ لِتَكُونَ حَظَّهُ مِنَ النَّارِ حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ قَالَ أَخْبَرَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ سُفْيَانَ الثَّوْرِيِّ عَنْ هِشَامِ بْنِ حَسَّانَ عَنِ الْحَسَنِ قَالَ كَانُوا يَرْتَجُونَ الْحُمَّى لَيْلَةً كَفَّارَةً لِمَا نَقَصَ مِنَ الذُّنُوبِ تَمَّ كِتَابُ الطِّبِّ وَيَلِيهِ كِتَابُ الْفَرَائِضِ
