Musnad Abu Ya'la al-Mawsili 106:19

Muhammad ibn Bakkar narrated to us, Abu Bakr ibn Ayyash narrated to us, Abu Ishaq narrated to us, from al-Bara’ who said: The Messenger of Allah (peace be upon him) went out with his companions, and we entered into the state of ihram for Hajj. When we arrived in Makkah, he said: "Make your Hajj an Umrah." Some people said: "O Messenger of Allah, we have already entered into the state of ihram for Hajj, so how can we make it an Umrah?" He said: "Look at what I have commanded you to do, and do it." They repeated the statement to him, so he became angry. Then he departed until he entered upon Aisha while he was angry. She saw the anger on his face and said: "Who has angered you? May Allah Almighty anger him." He said: "Why should I not be angry when I command a matter and it is not followed?"
