Fath al-Rabbani

It is narrated from Sayyiduna Anas (may Allah be pleased with him), he says: I was serving wine to Sayyiduna Abu Ubaidah bin Jarrah, Sayyiduna Ubayy bin Ka'b, Sayyiduna Suhail bin Bayda, and a group of the noble Companions at the house of Sayyiduna Abu Talhah (may Allah be pleased with him). The wine had almost begun to show its effect on them when a Muslim came and said: Do you not know that wine has been made forbidden? In response, they did not say, "Alright, we will see," or "We will ask someone else," rather, they immediately ordered: O Anas! Whatever is left in the vessel, pour it out. By Allah! After that, they never even looked at wine. In those days, wine was generally made from dried dates and unripe dates.
