Musnad Ahmad 1153:1006

'Affan narrated to us, Shu'bah narrated to us, he said: Abu Bakr ibn Hafs informed me, he said: I heard 'Urwah ibn al-Zubayr say: 'Aishah said: "What are they saying breaks the prayer?" He said: They say: The woman, the dog, and the donkey break the prayer. She said: "I have seen myself lying across between the hands of the Messenger of Allah (peace and blessings of Allah be upon him), like the lying of a funeral bier."
