Mukhtasar Bukhari (Abridged) 1027 — Selling grapes for grapes

Narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) forbade the sale of Muzabana, and Muzabana is to sell dried dates by measure in exchange for fresh dates, and to sell fresh grapes by measure in exchange for dried grapes.
