حَدَّثَنَا وَكِيعٌ، عَنِ ابْنِ أَبِي لَيْلَى، عَنِ الْمِنْهَالِ بْنِ عَمْرٍو، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، قَالَ كَانَ أَبِي يَسْمُرُ مَعَ عَلِيٍّ فَكَانَ عَلِيٌّ يَلْبَسُ ثِيَابَ الصَّيْفِ فِي الشِّتَاءِ وَثِيَابَ الشِّتَاءِ فِي الصَّيْفِ فَقِيلَ لَهُ لَوْ سَأَلْتَهُ فَسَأَلَهُ فَقَالَ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَعَثَ إِلَيَّ وَأَنَا أَرْمَدُ يَوْمَ خَيْبَرَ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنِّي رَمِدٌ فَتَفَلَ فِي عَيْنِي وَقَالَ اللَّهُمَّ أَذْهِبْ عَنْهُ الْحَرَّ وَالْبَرْدَ فَمَا وَجَدْتُ حَرًّا وَلَا بَرْدًا بَعْدُ قَالَ وَقَالَ لَأَبْعَثَنَّ رَجُلًا يُحِبُّهُ اللَّهُ وَرَسُولُهُ وَيُحِبُّ اللَّهَ وَرَسُولَهُ لَيْسَ بِفَرَّارٍ قَالَ فَتَشَرَّفَ لَهَا النَّاسُ قَالَ فَبَعَثَ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ .
It was narrated that ‘Abdur-Rahman bin Abi Laila said: My father used to stay up at night with ‘Ali, and ‘Ali used to wear summer clothes in winter and winter clothes in summer. It was said to me: Why don`t you ask him about that? So I asked him and he said: The Messenger of Allah (ﷺ) sent for me on the day of Khaibar and I had sore eyes, so I said:O Messenger of Allah (ﷺ), I have sore eyes. He spat in my eye and said: `O Allah, take away from him heat and cold.` And I have never felt heat or cold since them. And he said: `I 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.` The people hoped to be the one, and he sent ‘Ali (رضي الله عنه).
