Jabir said that God's Messenger cursed the one who accepted usury, the one who paid it, the one who recorded it, and the two witnesses to it, saying they were all alike.
‘Ubada b. as-Samit reported God's Messenger as saying, "Gold is to be paid for by gold, silver by silver, wheat by wheat, barley by barley, dates by dates, and salt by salt, like for like and equal for equal, payment being made on the spot. If these classes differ, sell as you wish if payment is made on the spot.”
