3. Ali has narrated from his father Muhammad ibn ‘Isma’il has narrated from al-Fadl ibn Shadhan all from Ibn Abi ‘Umayr from Hisham ibn al-Hakam who has said the following: “About the case of a man who buys certain goods with deferred payment for an appointed time, abu Ja‘far , has said, ‘He cannot buy it in the manner of Murabahah (capital plus profit) without deferment for an appointed time which is agreed upon; and if he sells in the manner of Murabahah (capital plus profit) without informing the party, then the one who has bought is entitled for a deferment of similar duration.’”
