Sahih al-Bukhari 3814

Sulayman ibn Harb narrated to us: Shuʿba narrated to us, from Saʿid ibn Abi Burda, from his father, who said: I came to Medina and met ʿAbdullah ibn Salam, may Allah be pleased with him. He said, “Come, so I can feed you sawīq and dates, and take you into a house.” Then he said, “You are in a land where usury is widespread. If you are owed something by a man and he gives you a gift—a load of straw, a load of barley, or a load of fodder—do not take it, for that is usury.” Al-Nadr, Abu Dawud, and Wahb did not mention “the house” in their reports from Shuʿba.
