I came saying who was prepared toexchange dirhams (for my gold), whereupon Talha b. Ubaidullah (Allah be pleased with him) (as he was sitting with 'Umar b. Khattib) said: Show us your gold and then come to us (at a later time). When our servant would come we would give you your silver (dirhams due to you). Thereupon 'Umar b. al-Khattib (Allah be pleased with him) said: Not at all. By Allah, either give him his silver (coins). or return his gold to him, for Allah's Messenger (ﷺ) said: Exchange of silver for gold (has an element of) interest in it. except when (it is exchanged) on the spot;and wheat for wheat is an interest unless both are handed over on the spot: barley for barley is interest unless both are handed over on the spot; dates for dates is interest unless both are handed over on the Spot.

I was in Syria (having) a circle (of friends). in which was Muslim b. Yasir. There came Abu'l-Ash'ath. He (the narrator) said that they (the friends) called him: Abu'l-Ash'ath, Abu'l-Ash'ath, and he sat down. I said to him: Narrate to our brother the hadith of Ubada b. Samit. He said: Yes. We went out on an expedition, Mu'awiya being the leader of the people, and we gained a lot of spoils of war. And there was one silver utensil in what we took as spoils. Mu'awiya ordered a person to sell it for payment to the people (soldiers). The people made haste in getting that. The news of (this state of affairs) reached 'Ubada b. Samit, and he stood up and said: I heard Allah's Messenger (ﷺ) forbidding the sale of gold by gold, and silver by silver, and wheat by wheat, and barley by barley, and dates by dates, and salt by salt, except like for like and equal for equal. So he who made an addition or who accepted an addition (committed the sin of taking) interest. So the people returned what they had got. This reached Mu'awiya. and he stood up to deliver an address. He said: What is the matter with people that they narrate from the Messenger (ﷺ) such tradition which we did not hear though we saw him (the Holy Prophet) and lived in his company? Thereupon, Ubida b. Samit stood up and repeated that narration, and then said: We will definitely narrate what we heard from Allah's Messenger (ﷺ) though it may be unpleasant to Mu'awiya (or he said: Even if it is against his will). I do not mind if I do not remain in his troop in the dark night. Hammad said this or something like this.

Dates are to be paid for by dates, wheat by wheat, barley by barley, salt by salt, like for like, payment being made on the spot. He who made an addition or demanded an addition, in fact, dealt in usury except in case where their classes differ.
