صحیح مسلم · Hadith 4065

Abu Sa'id al-Khudri (Allah be pleased with him) reported Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) as saying: Gold is to be paid for by gold, silver by silver, wheat by wheat, barley by barley, dates by dates, salt by salt, like by like, payment being made hand to hand. He who made an addition to it, or asked for an addition, in fact dealt in usury. The receiver and the giver are equally guilty.
