Musnad Ahmad 1153:848

Ali ibn Ishaq narrated to us, he said: Abdullah informed us, he said: Yunus informed us, from al-Zuhri, he said: Urwah narrated to me, from Aisha, that she said: "Does Abu Hurayrah not amaze you? He came and sat beside my chamber narrating from the Messenger of Allah, peace and blessings of Allah be upon him, making me hear that, while I was performing my prayer (tasbih). He stood up before I had finished my prayer. Had I caught up with him, I would have retorted to him: 'The Messenger of Allah, peace and blessings of Allah be upon him, did not recount the speech rapidly as you recount it.'"
