Musnad Abu Ya'la al-Mawsili 115:250

Zuhayr narrated to us, Abd al-Samad narrated to us, Hammam narrated to us, Qatadah narrated to us, he said: I asked Anas, "How many times did the Messenger of Allah (peace and blessings of Allah be upon him) perform Hajj?" He said: "One Hajj, and he performed four Umrahs: his Umrah from al-Hudaybiyyah, his Umrah from al-Ji'ranah in Dhu al-Qi'dah when he distributed the spoils of Hunayn, and his Umrah with his Hajj."
