What is the ruling on someone who swore by divorce not to sell a piece of furniture for a certain price? Does the divorce occur if he donates it or gifts it, or if it becomes dilapidated and cannot reach that price? Is it permissible for him to donate it or throw it away?

The answer given to you by the Sheikh is correct and aligns with our view on the matter. However, we would like to caution you that a permissible oath is sworn by Allah Almighty. As for swearing by divorce, it is among the oaths of the wicked, and it may lead to undesirable consequences.
