Narrated Abu Sa'eed:
The Prophet (ﷺ) prohibited mixing of unripe dates and dates, and mixing of raisins and dates (for making Nabidh), and he prohibited the jars that Nabidh is made in.
He said: There are narrations on this topic from Anas, Jabir, Abu Qatadah, Ibn 'Abbas, Umm Salamah, and Ma'bad bin Ka'b from his mother.
[Abu 'Eisa said:] This Hadith is Hasan Sahih.
