Abu Nadra reported: I asked Ibn 'Umar (RA) and Ibn Abbas (RA) 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 (RA) 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 ( صلی اللہ علیہ وسلم ) . There came to him the owner of a date-palm with one sa' of fine dates, and the dates of Allah's Apostle ( صلی اللہ علیہ وسلم ) were of that colour. Allah's Apostle ( صلی اللہ علیہ وسلم ) 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 ( صلی اللہ علیہ وسلم ) 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; (RA) . He (the narrator) said: Abu as-Sahba' narrated to me: He asked Ibn Abbas (RA) in Makkah, and he too disapproved of it.
