Majma al-Zawaid — Hadith 8159

Sharahil narrates: I said to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both): "What do you say about a man who takes a bunch of grapes, squeezes it and drinks it?" He said: "There is no harm in it." When he drinks it, he said: "Its drinking is lawful, and its selling is lawful."
Ahmad mentioned it within a long hadith. Its chain contains a narrator, Ibn Bukayl, and a narrator, Tayyaf, and I do not know either of them; the remaining narrators of this narration are thiqat (trustworthy).
