What are examples of "two conditions in one sale" from our contemporary reality, and does the sale contract become void and the money unlawful if two conditions are included in it?

Scholars have differed on the meaning of the prohibition of "two conditions in one sale," holding two views: 1. It includes stipulating two conditions, even if they are valid, but are not part of the contract's requirements, such as stipulating the carrying and breaking of wood after its purchase. 2. The intent behind the two conditions is that they lead to a religiously forbidden matter, such as usury (riba). This prohibition is interpreted to include "two sales in one sale" or " 'Inah sale," where one sells an item for a deferred price then buys it back for a lower cash price. This is the stronger opinion, and stipulating conditions that do not involve a prohibition, such as carrying and breaking, is permissible.

If the contract includes two forbidden conditions, such as 'Inah, it is a void contract, and the money earned from it is unlawful because it is usury.
