A Defective (Fasid) Condition in a Sale

Question

The hides of sacrificial animals are collected in one place, then sold, and the money is spent on its prescribed heads of expenditure. However, at the time of selling the hides, the condition is laid on the buyer: “However many hides are collected on the 11th and 12th of Dhu al-Hijja, you will have to buy them all at this same rate.” Is it correct to sell in this way or not?

Answer

Attaching conditions to a sale is something that renders the contract defective (fasid).
