Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) narrates that the Messenger of Allah (peace and blessings be upon him) forbade making nabidh (fermented drink) by mixing ghadir (half-ripe dates) with (fully) ripe dates, as well as by mixing dried grapes (raisins) and dates together. He also wrote to the people of Jurash instructing them not to make nabidh by mixing dried grapes and dates together.
