Is the owner entitled to the rent for the seven months after the cancellation of the machine sale contract due to the buyer's procrastination in payment, knowing that the buyer benefited from it throughout this period?

If the sale is concluded and the goods delivered, the seller has no right to cancel the sale except with the consent of both parties or for a permissible excuse. The buyer's insolvency permits rescission if the seller was unaware of it at the time of sale. However, if the seller knew of it, he does not have the right to rescind. Ibn Taymiyyah held that the seller has the right to rescind the sale if the buyer is solvent but procrastinates in paying the price.

If the sale is concluded after the lease is terminated or expires, the seller has no right to demand rent for the period during which the buyer used the machine. However, if the sale is concluded before the lease contract ends, the seller is entitled to rent only for the remaining period of the lease contract.
