Chapter: The Prohibition of selling silver for gold to be paid at a later date

My partner sold silver to be paid in the (Hajj) season or (in the days of) Hajj. He (my partner) came to me and informed me, and I said to him: Such transaction is not desirable. He said: I sold it in the market (on loan) but nobody objected to this. I went to al-Bara' b. 'Azib and asked him, and he said: Allah's Apostle (ﷺ) came to Medina and we made such transaction, whereupon he said: In case the payment is made on the spot, there is no harm in it, and in case (it is 'sold) on loan, it is usury. You better go to Zaid b. Arqam, for he is a greater trader than I; so I went to him and asked him, and he said like it.

I asked al-Bara' b. Azib about the exchange of (gold for silver or vice versa), whereupon he said: you better ask Zaid b. Arqam for he knows more than I. So I asked Zaid but he said: You better ask al-Bara' for he knows more than I. Then both of them said: Allah's Messenger (ﷺ) forbade the sale of silver for gold when payment is to be made in future.

It is to be made on the spot. This is what I heard (from Allah's Messenger (may peace be upon him ).

Allah's Messenger (ﷺ) prohibited us. The rest of the hadith is the same.
