It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he said: The command prohibiting wine was revealed concerning two tribes of the Ansar who drank wine until, when they became thoroughly drunk, they began to assault one another. When they came to their senses, a man would see the marks of wounds on his face, head and beard and say: "My brother so-and-so did this to me. By Allah! Had he been kind to me, he would not have done this." They were brothers and there was no rancour in their hearts, but the wine produced rancour. Then Allah, the Mighty and Majestic, revealed these verses: "O you who believe, wine and gambling" up to "so will you not desist?" [Surah al-Ma'idah: 90] . At this, some people said: "It is utter filth, yet it was in the stomachs of those who were martyred at Badr and Uhud." Then Allah, the Mighty and Majestic, revealed this verse: "There is no sin upon those who believe and do righteous deeds for what they ate" until He said: "and Allah loves those who do good." [Surah al-Ma'idah: 93]
