[4059] 79 - (1586) It was narrated from Mâlik bin Aws bin Al-Hadathân that he said: "I was going around saying: 'Who will exchange Dirham (for my gold)?' Talhah bin 'Ubaidullâh, who was with 'Umar bin Al-Khaţţâb, said: 'Show us your gold, then come to us later, when our servant comes, and we will give you your silver.' 'Umar bin Al-Khaţţâb said: 'No, by Allâh! Either give him his silver (now) or give him back his gold, for the Messenger of Allâh ﷺ said: "Silver for gold is Ribâ, unless it is exchanged on the spot; wheat for wheat is Ribâ, unless it is exchanged on the spot; barley for barley is Ribâ, unless it is exchanged on the spot; dates for dates is Ribâ unless it is exchanged on the spot."
