Musannaf Ibn Abi Shayba 38:10

Ibn Idris narrated to us, from Harun ibn Ibrahim, from Abdullah ibn Ubayd ibn Umayr: That al-Ashtar and Ibn al-Zubayr met. Ibn al-Zubayr said: "I did not strike him a single blow until he had struck me five or six times." He said: Then he said, "And he threw me by my legs, then said: 'By Allah, were it not for your kinship to the Messenger of Allah (may Allah bless him and grant him peace), I would not have left a single limb of yours attached to its companion.'" He said: And Aisha said, "Woe to Asma's bereavement." He said: Then, when some time had passed, she gave ten thousand to the one who brought her the glad tidings that he was alive.
