Hadith.4097 - Al-Hasan ibn Mahbub narrated from 'Abbad ibn Suhayb, who said
I asked Abu Abdullah (as) about an item held by two men, one of them claims, "I entrusted it to you as a deposit (wadi'ah)," while the other says, "It is collateral (rahn) with me."
Imam (as) said: "The statement of the one who claims it is collateral (rahn) is accepted unless the one who claims it was entrusted (wadi'ah) presents witnesses."
