What property is valid for hypothecation (Rahn)?

Primary text

Any item whose sale is permissible is also valid for hypothecation. The underlying purpose of hypothecation is to secure the debt so that it may be fulfilled from the price of the collateral if fulfillment from the debtor's personal liability becomes impossible. This condition is met by anything that can be sold. This view is held by Ibn Abi Layla, Malik, Al-Buti, Al-Awza'i, Suwar, Al-'Anbari, Al-Shafi'i, and Abu Thawr.
