Is it allowed for someone to sell a thing they have acquired ownership of before taking delivery of it?
Yes, it is permissible for a person to sell a thing they have acquired ownership of before taking delivery of it, unless the thing is foodstuffs in a commutative contract. In that case, it is not allowed to sell such goods by measure before taking delivery. However, if the goods are purchased as unascertained goods, they can be sold prior to taking delivery.
