Getting some furniture from another store and selling it to the buyer

A: Firstly: If you sell furniture in cash or in installments while possessing it, then the transaction will be valid. Secondly: If you sell furniture in cash or on deferred payment while you do not possess it, then this transaction will be invalid. The Prophet (peace be upon him) forbade a person selling what they do not posses in the Hadith reported by Hakim ibn Hizam. He said: "Do not sell what you do not possess!" May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
