LessonsBab al-Salam: Advance Price, Specified Goods, Delivery Date and ConditionsQuiz

The future goods must be quantified in units reproducible at the date of delivery. “One truckload of rice” is inadequate if the truck capacity is not fixed; “400 kg” identifies a legally examinable quantity. Without specification, neither the seller's obligation nor the buyer's entitlement is clear.
This is a core element of the seven conditions. Unless the quantity is known, the obligation remains disputable from the beginning; a standard weight, measure, count or length resolves the issue.
