Yahya related to me from Malik that Kathir ibn Farqad asked AbuBakr ibn Muhammad ibn Amr ibn Hazm about a man who sold food to bedelivered at a future date to a man for gold and then with the gold,he bought dates before he had taken delivery of the gold. Hedisapproved of that and forbade it.Yahya related to me fromMalik from Ibn Shihab the like of that.Malik said, ''Saidibn al-Musayyab, Sulayman ibn Yasar, Abu Bakr ibn Muhammad ibn Amr ibnHazm, and Ibn Shihab forbade that a man sell wheat for gold and thenbuy dates with that gold before he had received the gold from thetransaction in which he sold the wheat. There is no harm for someoneto buy dates on delayed terms, on the strength of the gold for whichhe sold the wheat, from someone other than the person to whom he soldthe wheat before taking possession of the gold, and to refer the onefrom whom he bought the dates to his debtor who bought the wheat, forthe gold he is owed for the dates."Malik said, "I asked morethan one of the people of knowledge about that and they did not seeany harm in it."
