Sayyiduna Ibn Umar (may Allah be pleased with them both) says: "Every intoxicant is wine, and every intoxicant is unlawful."
All the other students of Malik narrated it from Malik like this as mawquf (a statement of Ibn Umar), except Rawh, who narrated it as marfu' in the narration of al-Dulabi from him; and Allah knows best.
