Musnad Ahmad 307:4

'Abd al-Samad narrated to us, he said: Shu'bah narrated to us, he said: Abu Bakr ibn Hafs narrated to us, from al-Agharr, from another man, from Abu Hurayrah, that the Prophet, peace and blessings of Allah be upon him, said: "Perform ablution from what the fire has changed." He said: And Abu Bakr—meaning Ibn Hafs—said: Al-Zuhri narrated to us, from Ibn Abi Talhah, from his father, from the Prophet, peace and blessings of Allah be upon him, the like of it. He said: And Shu'bah narrated to us, from al-A'mash, from Abu Salih, from Abu Hurayrah, from the Prophet, peace and blessings of Allah be upon him, the like of it.
