Is it permissible to rent items like musk, sandalwood, camphor pieces, and aloe wood for temporary use?

Primary text

Renting items whose fragrance or essence remains, such as musk, sandalwood, camphor pieces, and aloe wood, for patients or others to smell for a period before returning them is permissible. This is because the benefit derived—the enjoyment of the scent—is a permissible utility. This action is analogous to renting for weighing or measuring, even though the rented item will naturally suffer wear and deterioration (iqhilaq and bala) during the rental period.
