And Abu Bakr ibn Ishaq narrated to me, saying: 'Affan ibn Muslim narrated to us, saying: Aban al-'Attar narrated to us, saying: Yahya ibn Abi Kathir narrated to me, saying: 'Abdullah ibn Abi Qatadah narrated to me, from his father, that the Prophet of Allah, peace and blessings be upon him, forbade mixing dates with unripe dates, and forbade mixing raisins with dates, and forbade mixing ripe dates with fresh dates. And he said: "Make nabidh from each one separately."
