3504. 'Amr bin Shu'aib narrated: "My father told me, from my grandfather" – until he mentioned Abdullāh bin 'Amr – "who said: The Messenger of Allāh ﷺ said: "It is not permissible to transact a loan combined with a sale, or to stipulate two conditions in one transaction, or to make a profit on something that you do not possess, or to sell something that is not with you." (Sahih)
