#1753 Narrated Al-Bara' :
"The Prophet (ﷺ) sent two armies, place 'Ali bin Abi Talib as the commanded of one of them, and Khalid bin Al-Walid over the other. He said: 'Where there is fighting, then 'Ali (is in command).'" He said: "So 'Ali conquered a fortress and took a slave girl. Khalid wrote a letter and sent me with it to the Prophet (ﷺ), to speak against him for it. So I arrived to the Prophet (ﷺ) to read the letter. The color of his face changed, the he said: 'What do you think about a man who loves Allah and His Messenger, and Allah and His Messenger love him?'" He said: "I said: 'I seek refuge from angering Allah and angering His Messenger, I am only the Messenger.' So he was silent.


There is something about this from Ibn 'Umar. This Hadith is Hasan Gharib, we do not know of it except from the narration of Al-Ahwas bin Jawwab. And his saying: "To speak against him for that." refers to An-Namimah.
