Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Saeed bin Jubair, he says that a man asked him and said: We intend to use raisins, so we wash off their dust, then we put them in a large pitcher or a large jar, and then we leave them like this for two months in winter and for a shorter period in summer? Upon this, Hazrat Saeed bin Al-Musayyib said: This is exactly what wine (khamr) is, so you should avoid it.
