وتسمية المكان الذي يوافيه فيه إذا كان له حمل ومؤنة
Translation: The place of delivery must be designated when the goods require carriage and expense.
For bulky or costly goods, the delivery location can materially change the seller's expense. Delivering 400 kg of rice to a nearby market is not equivalent to transporting it to a warehouse in another city. Abu Hanifa requires the location to be specified where the promised goods involve significant carriage and cost.
For something negligible to transport, the same additional stipulation does not operate in the same form. The rule prevents disputes about who bears the burden of transportation.
