Musannaf Ibn Abi Shaybah 25588 — Mixing unripe dates, dates

Ikrimah reports concerning Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he disliked semi-ripe dates on their own, and he also disliked putting semi-ripe and ripe dates together. But he saw no harm in putting raisins and dates together, and he used to say: These are two lawful things, whether together or separate.
