Sahih al-Bukhari 3973
Narrated 'Urwa (the son of Az- Zubair):
Az-Zubair had three scars 
     caused by the sword, one of which was over his shoulder and I used to 
     insert my fingers in it. He received two of those wounds on the day of
     Badr and one on the day of Al-Yarmuk. When 'Abdullah bin Zubair was 
     killed, 'Abdul-Malik bin Marwan said to me, "O 'Urwa, do you recognize
     the sword of Az-Zubair?" I said, "Yes." He said, "What marks does it 
     have?" I replied, "It has a dent in its sharp edge which was caused in
     it on the day of Badr." 'Abdul- Malik said, "You are right! (i.e. 
     their swords) have dents because of clashing with the regiments of the
     enemies Then 'Abdul-Malik returned that sword to me (i.e. Urwa). 
     (Hisham, 'Urwa's son said, "We estimated the price of the sword as 
     three-thousand (Dinars) and after that it was taken by one of us (i.e.
     the inheritors) and I wish I could have had it.")
