‘Do not make Nabidh with dried dates and unripe dates together, make Nabidh with each of them on its own.”
Sunan Ibn Majah Book 30, Hadith 26
← Previous Hadith It was narrated from Jabir bin ‘Abdullah that the Messenger of Allah (ﷺ) forbade making Nabidh* with dates and raisins together, or with unripe dates and fresh dates together.”

Another chain reports the same.
