Hazrat Bara bin Azib (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) sent two armies, appointing Hazrat Ali (may Allah be pleased with him) as the commander of one and Hazrat Khalid bin Walid (may Allah be pleased with him) as the commander of the other. Then he said: If there is fighting, then in that case Hazrat Ali (may Allah be pleased with him) will be the commander over the people. So Hazrat Ali (may Allah be pleased with him) conquered the fort and chose a slave woman for himself. Upon this, Hazrat Khalid (may Allah be pleased with him) wrote a letter and informed the Prophet صلی اللہ علیہ وسلم about this matter. When the Messenger of Allah (peace and blessings be upon him) read this letter, he said: What do you say about a person who loves Allah and His Messenger صلی اللہ علیہ وسلم , and Allah and His Messenger صلی اللہ علیہ وسلم love him?
