Hadith text

Narrated Abu Sa`id al-Khudri:Once Bilal brought Barni (i.e. a kind of dates) to the Prophet (ﷺ) and the Prophet (ﷺ) asked him, "From where have you brought these?" Bilal replied, "I had some inferior type of dates and exchanged two Sas of it for one Sa of Barni dates in order to give it to the Prophet; to eat." Thereupon the Prophet (ﷺ) said, "Beware! Beware! This is definitely Riba (usury)! This is definitely Riba (Usury)! Don't do so, but if you want to buy (a superior kind of dates) sell the inferior dates for money and then buy the superior kind of dates with that money

Abu Saeed Al-Khudri (رضی اللہ عنہ) bataate hain: Ek baar Bilal Barni (ek khaas qisam ki khajoor) Nabi ke paas laaye, aur Nabi ne unse pucha: "Yeh kahan se laaye?" Bilal ne jawab diya: "Mere paas kam quality wali khajoor thi aur maine uski do Sa badalkar ek Sa Barni khajoor li taake main use Nabi ko khane ke liye de sakoon." Isspar Nabi ne kaha: "Khabardar! Khabardar! Yeh zaroor sood (Riba) hai! Yeh zaroor Riba hai! Aisa mat karo, magar agar tum (behtar quality) khareedna chahte ho, kam quality wali khajoor ko paisa ke badle becho, phir usse behtar khajoor khareed lo."
