Buying and selling a commodity before paying its price
Is it permissible for a buyer to take profit for a commodity bought at the expenses of someone else who both gives him the profit and pays the price of the commodity to the first seller.
It is permissible for someone, who buys a commodity which comes into his possession after the sale contract is concluded, to sell it at a profit which he may receive even before paying the price to the first seller. The second buyer has to pay the price to the first seller. (Part No. 13; Page No. 257)
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
