I once asked abu al-Hassan (a.s.), about the case of a man whose brother had died and left a box in which there were al-Rahn (security deposit) goods, of which certain ones had the name of the owner on them and others did not have any names on them and for how much they were left as al- Rahn (security deposit), and what do you say about that with an unknown owner. He (the Imam) said, ‘It is like his own property.’”
