Does minor utilization of an item, such as riding a beast to check its gait or leading it to the seller, void the right of rescission for a defect?

If the buyer rides the beast merely to observe its gait, to water it, or to return it to the seller, the option is not voided. Similarly, if the female slave is used only for testing her condition, or the shirt is worn only to ascertain its proper size, the option remains valid because these acts do not constitute acceptance of the defective item, just as they do not void the option stipulated in a condition (khiyar al-shart).

If the use is excessive and not specific to testing, the right to return is voided. However, if the use is minor and does not imply ownership, the option is not invalidated.
