[Machine] We were raiding and Ma'awiya was with us. We obtained gold and silver, so Ma'awiya ordered a man to sell it to the people at their own rates. The people rushed to buy, and 'Ubadah bin As-Samit got up and warned them against it (i.e. against the purchase of gold in exchange for silver). Then 'Ubadah got up again and said, "I testified that I heard Allah's Messenger ﷺ saying, 'The selling of gold for silver is Riba (usury), except if it be by like for like, and similarly, the selling of wheat for wheat is Riba (usury) unless it be by like for like. And the selling of barley for barley is usury unless it be by like for like.'"
