Is it permissible for a master to sell an item on credit (nasi'ah)?

Primary text

It is not permissible for the master to sell an item on credit, even if the sale price is multiple times its actual value. This is the position of Al-Shafi'i because such a transaction involves deception (taghrir) concerning wealth, which is prohibited due to the right the master holds over the wealth. This prohibition remains whether the master takes a guarantor, a pledge (rahn), or nothing for the deferred payment because the element of risk (gharar) is not removed, as the pledge might be destroyed, or the debtor and the guarantor might become bankrupt.
