A man who gives another man wealth in mudarabah

Harun said: I asked al-Hakam and Hammad about a man who gave another man wealth as a mudarabah and called witnesses to it against him. Then that man came wanting to take back his wealth from him, and he said: "I have already handed it over to you." Al-Hakam said: He must produce witnesses that he handed it back, just as the owner of the wealth called witnesses against him.

And Hammad said: He is to be believed in this, just as he is believed in similar matters.
