Abd Sa'id reported:Bilal (Allah be pleased with him) came with fine quality of dates. Allah's Messenger (ﷺ) said to him: From where (you have brought them)? Bilal said: We had inferior quality of dates and I exchanged two sa's (of inferior quality) with one sa (of fine quality) as food for Allah's Apostle (ﷺ), whereupon Allah's Messenger (ﷺ) said: Woe! it is in fact usury; therefore, don't do that. But when you intend to buy dates (of superior quality), sell (the inferior quality) in a separate bargain and then buy (the superior quality). And in the hadith transmitted by Ibn Sahl there is no mention of" whereupon

Abu Sa'id (Allah be pleased with him) reported:Dates were brought to Allah's Messenger (ﷺ), and he said: These dates are not like our dates, whereupon a man said: We sold two sa's of our dates (in order to get) one sa', of these (fine dates), whereupon Allah's Messenger (ﷺ) said: That is interest; so return (these dates of fine quality), and get your (inferior dates) ; then sell our dates (for money) and buy for us (with the help of money) such (fine dates)

Abu Nadra reported:I asked Ibn Abbas (Allah be pleased with them) about the conversion (of gold and silver for silver and gold). We said: Is it hand to hand exchange? I said: Yes. whereupon he said: There is no harm in it. I informed Abu Sa'id about it, telling him that I had asked Ibn 'Abbas about it and he said: Is it hand to hand exchange? I said: Yes, whereupon he said: There is no harm in it. He (the narrator) said, or he said like it: We will soon write to him, and he will not give you this fatwa (religious verdict). He said: By Allah, someone of the boy-servants of Allah's Messenger (ﷺ) brought dates, but he refused to accept them (on the plea) that those did not seem to be of the dates of our land. He said: Something had happened to the dates of our land, or our dates. So I got these dates (in exchange by giving) excess (of the dates of our land), whereupon he said: You made an addition for getting the fine dates (in exchange) which tantamounts, to interest; don't do that (in future). Whenever you find some doubt (as regards the deteriorating quality of) your dates, sell them, and then buy the dates that you like

Abu Nadra reported:I asked Ibn Umar and Ibn Abbas (Allah be pleased with them) about the conversion of gold with gold but they did not find any harm in that. I was sitting in the company of Abd Sa'id al-Khudri (Allah be pleased with him) and asked him about this exchange, and he said: Whatever is addition is an' interest. I refused to accept it on account of their statement (statement of Ibn 'Abbas and Ibn 'Umar). He said: I am not narrating to you except what I heard from Allah's Messenger (ﷺ). There came to him the owner of a date-palm with one sa' of fine dates, and the dates of Allah's Apostle (ﷺ) were of that colour. Allah's Apostle (ﷺ) said to him: Where did you get these dates? I went with two sa's of (inferior dates) and bought one sa' of (these fine dates), for that is the prevailing price (of inferior dates) in the market and that is the price (of the fine quality of dates in the market), whereupon Allah's Messenger (ﷺ) said: Woe be upon you! You have dealt in interest, when you decide to do it (i. e. exchange superior quality of dates for inferior quality) ; so you should sell your dates for another commodity (or currency) and then with the help of that commodity buy the dates you like. Abu Sa'ad said: When dates are exchanged for dates (with different qualities) there is the possibility (of the element of) interest (creeping into that) or when gold is exchanged for gold having different qualities. I subsequently came to Ibn 'Umar and he forbade me (to do it), but I did not come to Ibn 'Abbas; (Allah be pleased with them). He (the narrator) said: Abu as-Sahba' narrated to me: He asked Ibn Abbas (Allah be pleased with them) in Mecca, and he too disapproved of it
