My father used to chat at night with ʿAli, and ‘Ali used to wear summer clothes in the winter and winter clothes in the summer. It was said to him: Why donʿt you ask him [about that]? He asked him and he said: The Messenger of Allah ﷺ sent for me when I had a sore eye on the day of Khaibar. I said: O Messenger of Allah, my eye is sore. He spat in my eye and said: ʿO Allah, take away heat and cold from him.” And I have never felt any heat or cold since that day. And he [the Prophet ﷺ] said: ʿI shall certainly give the banner to a man who loves Allah and his Messenger, and Allah and His Messenger love him, and he is not one to runaway.ʿ The Companions of the Prophet ﷺ hoped for it, but he gave it to me.  

كَانَ أَبِي يَسْمُرُ مَعَ عَلِيٍّ وَكَانَ عَلِيٌّ يَلْبَسُ ثِيَابَ الصَّيْفِ فِي الشِّتَاءِ وَثِيَابَ الشِّتَاءِ فِي الصَّيْفِ فَقِيلَ لَهُ لَوْ سَأَلْتَهُ؟ فَسَأَلَهُ فَقَالَ إِنَّ رَسُولَ اللهِ ﷺ بَعَثَ إِلَيَّ وَأَنَا أَرْمَدُ الْعَيْنِ يَوْمَ خَيْبَرَ فَقُلْتُ يَا رَسُولَ اللهِ إِنِّي أَرْمَدُ الْعَيْنِ قَالَ فَتَفَلَ فِي عَيْنِي وَقَالَ اللهُمَّ أَذْهِبْ عَنْهُ الْحَرَّ وَالْبَرْدَ فَمَا وَجَدْتُ حَرًّا وَلا بَرْدًا مُنْذُ يَوْمِئِذٍ وَقَالَ لاعْطِيَنَّ الرَّايَةَ رَجُلًا يُحِبُّ اللهَ وَرَسُولَهُ وَيُحِبُّهُ اللهُ وَرَسُولُهُ لَيْسَ بِفَرَّارٍ فَتَشَرَّفَ لَهَا أَصْحَابُ النَّبِيِّ ﷺ فَأَعْطَانِيهَا

And he said: ʿI shall send out a man who loves Allah and His Messenger, and Allah and His Messenger love him, and he is not one to run away.ʿ The people hoped to be the one, and he sent ‘Ali ؓ .  

كَانَ أَبِي يَسْمُرُ مَعَ عَلِيٍّ فَكَانَ عَلِيٌّ يَلْبَسُ ثِيَابَ الصَّيْفِ فِي الشِّتَاءِ وَثِيَابَ الشِّتَاءِ فِي الصَّيْفِ فَقِيلَ لي لَوْ سَأَلْتَهُ عن هذا؟ فَسَأَلتهُ فَقَالَ إِنَّ رَسُولَ اللهِ ﷺ بَعَثَ إِلَيَّ وَأَنَا أَرْمَدُ يَوْمَ خَيْبَرَ فَقُلْتُ يَا رَسُولَ اللهِ إِنِّي رَمِدٌ فَتَفَلَ فِي عَيْنِي وَقَالَ اللهُمَّ أَذْهِبْ عَنْهُ الْحَرَّ وَالْبَرْدَ فَمَا وَجَدْتُ حَرًّا وَلا بَرْدًا بَعْدُقَالَ وَقَالَ لابْعَثَنَّ رَجُلًا يُحِبُّهُ اللهُ وَرَسُولُهُ وَيُحِبُّ اللهَ وَرَسُولَهُ لَيْسَ بِفَرَّارٍ قَالَ فَتَشَرَّفَ لَهَا النَّاسُ قَالَ فَبَعَثَ عَلِيًّا  

[Machine] He said to Ali, who was accompanying him, "Indeed, people have criticized you for going out in extreme cold while wearing thin clothing and going out in extreme heat while wearing thick clothing." Ali said, "Were you not with us at the Battle of Khaybar?" He said, "Yes." Ali said, "The Messenger of Allah ﷺ sent Abu Bakr with a battalion and he returned. Then he sent Umar with a battalion and he also returned with the people." So the Messenger of Allah ﷺ said, "I will give the flag to a man who loves Allah and His Messenger and whom Allah and His Messenger love, and he will not flee." Then he sent for me while I was sharpening my weapon. I said, "I am sharpening (my weapon), so pour some water into my eyes." And he said, "O Allah, protect him from the heat and the cold, for I have not found anyone after him who is affected by either heat or cold."  

أَنَّهُ قَالَ لِعَلِيٍّ وَكَانَ يَسِيرُ مَعَهُ «إِنَّ النَّاسَ قَدْ أَنْكَرُوا مِنْكَ أَنَّكَ تَخْرُجُ فِي الْبَرْدِ فِي الْمُلَاءَتَيْنِ وَتَخْرُجُ فِي الْحَرِّ فِي الْحَشْوِ وَالثَّوْبِ الْغَلِيظِ» قَالَ «أَوَلَمْ تَكُنْ مَعَنَا بِخَيْبَرَ؟» قَالَ بَلَى قَالَ «فَإِنَّ رَسُولَ اللهِ ﷺ بَعَثَ أَبَا بَكْرٍ وَعَقَدَ لَهُ لِوَاءً فَرَجَعَ وَبَعَثَ عُمَرَ وَعَقَدَ لَهُ لِوَاءً فَرَجَعَ بِالنَّاسِ» فَقَالَ رَسُولُ اللهِ ﷺ «لَأُعْطِيَنَّ الرَّايَةَ رَجُلًا يُحِبُّ اللهَ وَرَسُولَهُ وَيُحِبُّه اللهُ وَرَسَولُهُ لَيْسَ بِفَرَّارٍ» فَأَرْسَلَ إِلَيَّ وَأنا أَرْمَدُ قُلْتُ «إِنِّي أَرْمَدُ فَتَفَلَ فِي عَيْنِي» وَقَالَ «اللهُمَّ اكْفِهِ أَذَى الْحَرِّ وَالْبَرْدِ فَمَا وَجَدْتُ حَرًّا بَعْدَ ذَلِكَ وَلَا بَرْدًا»
