Narrated `Urwa:
Az-Zubair said, "I met Ubaida bin Sa`id bin Al-As on the day (of the battle) of Badr and he was
covered with armor; so much that only his eyes were visible. He was surnamed Abu Dhat-al-Karish.
He said (proudly), 'I am Abu-al-Karish.' I attacked him with the spear and pierced his eye and he died.
I put my foot over his body to pull (that spear) out, but even then I had to use a great force to take it
out as its both ends were bent." `Urwa said, "Later on Allah's Apostle asked Az-Zubair for the spear
and he gave it to him. When Allah's Apostle died, Az-Zubair took it back. After that Abu Bakr
demanded it and he gave it to him, and when Abu Bakr died, Az-Zubair took it back. `Umar then
demanded it from him and he gave it to him. When `Umar died, Az-Zubair took it back, and then
`Uthman demanded it from him and he gave it to him. When `Uthman was martyred, the spear
remained with `Ali's offspring. Then `Abdullah bin Az-Zubair demanded it back, and it remained with
him till he was martyred.
