Rafi' bin Khadij and Sahl bin Abi Hathmah narrated to him that the Messenger of Allah (ﷺ) prohibited Al-Muzabanah sales, (buying) fruits with dried dates, except for those who practice Al-'Araya - for he permitted it for them - and from buying grapes with raisins, and from every fruit by its estimation.

This Hadith is Hasan Sahih Gharib from this route.
