Selling an item before taking possession of it
Q: Salmaan owns a grocery store. Ismail phoned him and purchased a pack of long life milk from him. After concluding the sale on the phone, Ismail did not take possession of the milk but instead sold the milk to Bakr and asked Salmaan to deliver the milk directly to Bakr instead of bringing it to his store. Is it correct for Ismail to sell the milk to Bakr before taking possession of it?
