Abu Sa'id (RA) reported: Dates were brought to Allah's Messenger ( صلی اللہ علیہ وسلم ) , 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 ( صلی اللہ علیہ وسلم ) 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).
