It is narrated from Qatadah: I asked Sa'id bin al-Musayyib about taking two live goats in exchange for one live goat. He said that a man had asked Sayyiduna Umar bin al-Khattab (may Allah be pleased with him), whereupon Sayyiduna Umar (may Allah be pleased with him) said: "Indeed, the last ruling Allah Almighty sent down was the verse of usury (riba), and the Prophet (peace and blessings be upon him) passed away from this world before he explained it (in detail). So leave usury and also everything in which there is doubt (of usury)!" I (Ibn Hajar) say: Ibn Majah recorded this narration without the opening question.
