Musnad Ahmad 1153:1222

'Uthman ibn 'Umar narrated to us, Yunus narrated to us, from al-Zuhri, from 'Urwah, who said: 'A'ishah said to me: "Does Abu Hurayrah not amaze you? He came and sat beside my chamber narrating from the Messenger of Allah (may Allah bless him and grant him peace), making me hear that, while I was performing my voluntary prayer. He stood up before I had finished my prayer. Had he sat until I finished my prayer, I would have replied to him: 'The Messenger of Allah (may Allah bless him and grant him peace) did not recite the hadith rapidly as you recite it.'"
