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. (Using translation from Muslim 2575)   

أَنَّ رَسُولَ اللهِ ﷺ دَخَلَ عَلَى أُمِّ السَّائِبِ أَوْ أُمِّ الْمُسَيَّبِ وَهِيَ تُرَفْرِفُ فَقَالَ مَا لَكِ يَا أُمَّ السَّائِبِ؟ أَوْ يَا أُمَّ الْمُسَيَّبِ قَالَتِ الْحُمَّى لَا بَارَكَ اللهُ فِيهَا فَقَالَ لَا تَسُبِّي الْحُمَّى؛ فَإِنَّهَا تُذْهِبُ خَطَايَا بَنِي آدَمَ كَمَا يُذْهِبُ الْكِيرُ خَبَثَ الْحَدِيدِ  

[Machine] Indeed, the Companions of our Prophet who embraced Islam passed away and did not leave behind any wealth. We have received wealth for which we could not find a place except for the ground. Then we brought it back to him another time, and he was constructing a wall for himself. He said, "Verily, a Muslim is rewarded for every expenditure he makes, except for something he puts in the ground. If it were not for the fact that the Messenger of Allah prohibited us from supplicating for death, I would have supplicated for it."  

إِنَّ أَصْحَابَ نَبِيِّنَا ﷺ الَّذِينَ أَسْلَمُوا مَضَوْا وَلَمْ يَنْقُصْهُمْ أَمْوَالٌ وَإِنَّا أَصَبْنَا مَالًا لَمْ نَجِدْ لَهُ مَوْضِعًا إِلَّا التُّرَابَ ثُمَّ أَتَيْنَاهُ مَرَّةً أُخْرَى نَعُودُهُ وَهُو يَبْنِي حَائِطًا لَهُ فَقَالَ إِنَّ الْمُسْلِمَ يُؤْجَرُ فِي كُلِّ شَيْءٍ يُنْفِقُهُ إِلَّا فِي شَيْءٍ يَجْعَلُهُ فِي التُّرَابِ وَلَوْلَا أَنَّ رَسُولَ اللهِ ﷺ نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ لَدَعَوْتُ بِهِ  

I heard Messenger of Allah ﷺ saying, "The good deeds of any person will not make him enter Paradise." (i.e., None can enter Paradise through his good deeds.) They (the Prophet's companions) said, 'Not even you, O Messenger of Allah ﷺ?' He said, "Not even myself, unless Allah bestows His favor and mercy on me." So be moderate in your religious deeds and do the deeds that are within your ability: and none of you should wish for death, for if he is a good doer, he may increase his good deeds, and if he is an evil doer, he may repent to Allah." (Using translation from Bukhārī 5673)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَنْ يُدْخِلَ الْجَنَّةَ أَحَدًا عَمَلُهُ قَالُوا وَلَا أَنْتَ يَا رَسُولَ اللهِ؟ قَالَ وَلَا أَنَا إِلَّا أَنْ يَتَغَمَّدَنِي اللهُ مِنْهُ بِفَضْلٍ وَرَحْمَةٍ فَسَدِّدُوا وَقَارِبُوا وَلَا يَتَمَنَّى أَحَدُكُمُ الْمَوْتَ إِمَّا مُحْسِنًا فَلَعَلَّهُ أَنْ يَزْدَادَ وَإِمَّا مُسِيئًا فَلَعَلَّهُ أَنْ يَسْتَعْتِبَ  

Abu Huraira narrated to us ahadith from Messenger of Allah ﷺ and out of these one is that Messenger of Allah ﷺ said: None amongst you should make a request for death, and do not call for it before it comes, for when any one of you dies, he ceases (to do good) deeds and the life of a believer is not prolonged but for goodness. (Using translation from Muslim 2682)   

وَقَالَ رَسُولُ اللهِ ﷺ لَا يَتَمَنَّى أَحَدُكُمُ الْمَوْتَ وَلَا يَدْعُو بِهِ مِنْ قَبْلِ أَنْ يَأْتِيَهُ إِنَّهُ إِذَا مَاتَ أَحَدُكُمُ انْقَطَعَ عَمَلُهُ عَنْهُ وَإِنَّهُ لَا يَزِيدُ الْمُؤْمِنَ عُمْرُهُ إِلَّا خَيْرًا  

The Prophet ﷺ said, "None of you should wish for death because of a calamity befalling him; but if he has to wish for death, he should say: "O Allah! Keep me alive as long as life is better for me, and let me die if death is better for me.' " (Using translation from Bukhārī 5671)   

قَالَ رَسُولُ اللهِ ﷺ لَا يَتَمَنَّيَنَّ أَحَدُكُمُ الْمَوْتَ مِنْ ضُرٍّ أَصَابَهُ فَإِنْ كَانَ لَا بُدَّ فَاعِلًا فَلْيَقُلِ اللهُمَّ أَحْينِي مَا كَانَتِ الْحَيَاةُ خَيْرًا لِي وَتَوَفَّنِي إِذَا كَانَتِ الْوَفَاةُ خَيْرًا لِي
