Musannaf Ibn Abi Shaybah

Hazrat Abdur Rahman bin Jubair bin Nafeer (may Allah have mercy on him) narrates that when the grief of the Companions (may Allah be pleased with them) exceeded all bounds at the martyrdom of Hazrat Zaid (may Allah be pleased with him) in the Battle of Mu'tah, the Messenger of Allah (peace and blessings be upon him) said: "Hazrat Masih (peace be upon him) will find among this Ummah some people who are like you or even better than you (he said this three times). Allah Almighty will never leave this Ummah helpless and without support, whose beginning is with me and whose end is with Hazrat Masih (peace be upon him)."
