Saad bin Abu Waqqas reported,

I came upon a group of the Ansar and the Muhajirun, and they said, "Come, we will feed you and give you wine to drink." This was before wine had been forbidden.He said, I went to them in a hashsh (which is a garden), and there was a roasted camel's head before them and a skin of wine. So I ate and drank with them.Then the Ansar and the Muhajirun were mentioned among them, and I said, "The Muhajirun are better than the Ansar."A man took one of the two jawbones of the head and struck me with it, wounding my nose. So I went to the Messenger of Allah ﷺ and informed him, and Allah revealed concerning him, meaning himself, regarding the matter of wine, "Intoxicants, gambling, idolatrous altars, and divining arrows are but defilement from the work of Satan" [Maidah 5:90].

عن سعد بن أبي وقاص قال

… أتيت على نفر من الأنصار والمهاجرين، فقالوا: تعال نطعمك ونسقك خمرا وذلك قبل أن تحرم الخمر، قال: فأتيتهم في حش،- والحش: البستان- فإذا رأس جزور مشوي عندهم، وزق من خمر، قال: فأكلت وشربت معهم، قال: فذكرت الأنصار والمهاجرين عندهم، فقلت: المهاجرون خير من الأنصار، قال: فأخذ رجل أحد لحيي الرأس، فضربني به فجرح بأنفي، فأتيت رسول الله ﷺ فأخبرته، فأنزل الله عز وجل في-يعني نفسه- شأن الخمر: {إنما الخمر والميسر والأنصاب والأزلم رجس من عمل الشيطن}.
