مسند أحمد

It was narrated that ‘Abdur-Rahman bin Abi Laila said: My father used to chat at night with `Ali, and ‘Ali used to wear summer clothes in the winter and winter clothes in the summer. It was said to him: Why don`t 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: `O 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: `I 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.` The Companions of the Prophet (ﷺ) hoped for it, but he gave it to me.
