Musnad Ahmad 30:1371

Yunus and Hajjaj narrated to us, they said: Layth narrated to us. Hajjaj said in his narration: Sa'id ibn Abi Sa'id narrated to me, from his father, from Abu Hurayrah, that the Messenger of Allah (peace and blessings of Allah be upon him) [said]—and Yunus said: From Sa'id, from his father, from Abu Hurayrah, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no prophet among the prophets but that he was given of the signs what the like of it would cause mankind to believe. And indeed, what I have been given is a revelation that Allah, the Mighty and Majestic, revealed to me. And I hope that I will be the one among them with the most followers on the Day of Resurrection."
