Musnad Abu Ya'la al-Mawsili 153:172

Ahmad ibn ‘Isa narrated to us, ‘Abdullah ibn Wahb narrated to us, ‘Umar ibn Muhammad informed me that his father narrated to him, from ‘Abdullah ibn ‘Umar, who said: We were speaking during the Farewell Pilgrimage, and the Messenger of Allah (may Allah bless him and grant him peace) was among us, and we did not know what the Farewell Pilgrimage was. The Messenger of Allah praised Allah and extolled Him, then he mentioned the False Messiah (al-Masih al-Dajjal) and spoke at length about him. Then he said: "Allah has not sent a prophet but that he warned his nation about him. Noah warned his nation about him, and the prophets after him. He will emerge among you, and what is hidden from you regarding his affair is not hidden from you: he is one-eyed in his right eye, as if it were a floating grape." Then he said: "Indeed, Allah has made your blood and your wealth sacred, like the sanctity of this day of yours, in this land of yours, in this month of yours. Have I conveyed the message?" They said: "Yes." He said: "O Allah, bear witness." Then he said: "Woe to you—or may you be spared—do not return after me as disbelievers, striking the necks of one another."
