Musannaf Ibn Abi Shaybah 21514 — If the pledger and the pledgee differ

Hammad was asked about a man who has a pledge in his possession and says: It is for ten dirhams, while its owner says: It is for one dirham; what is the ruling in this case? He said: Testimony is required of the one who claims the excess, just as, if one claims it is a pledge and the other that it is a trust, the word of the owner prevails.
