The Prophet ﷺ said, "Do not combine fresh dates with unripe dates, nor raisins with dried dates, when making nabidh."
حدثنا عبد الرزاق أخبرنا ابن جريج وروح قال حدثنا ابن جريج قال قال عطاء وقال روح في حديثه قال وقال لي عطاء سمعت
قال النبي ﷺ لا تجمعوا بين الرطب والبسر والزبيب والتمر نبيذا
Its isnad is sahih. The prohibition against combining fresh dates and unripe dates has already appeared. This marfu narration was transmitted by Muslim with its exact wording and chain, 3/1574, no. 1986 (repeated), in the Book of Drinks, on the dislike of steeping dates and raisins mixed together. Ibn Majah, 2/1126, no. 3397, and Ibn Abu Shayba, 7/542, no. 4084.
