Is it valid for the agent to sell the item on credit (*nasi'ah*)?

Primary text

The sale conducted on credit is invalid because the unqualified authorization to sell implies a cash transaction (*naqd*). Credit introduces the harm of delay and financial risk, which should only be accepted if the principal benefits from the profit in compensation. In this specific arrangement, the principal has no benefit from the profit in any case. Furthermore, the primary purpose of *mudarabah* is realizing profit, which is usually higher in credit sales, but here the principal's goal is not profit, nor does he have any share in it, rendering the credit sale of no benefit to him.
