Musannaf Ibn Abi Shaybah 38524 — the first to do a thing, and who did

Abu al-Aliyah reported from a slave of Sayyiduna Salman (may Allah be pleased with him), who was called Suwayd and of whom he spoke well, that he said: When the Muslims conquered al-Mada'in and set out in pursuit of the enemy, I found a basket. Sayyiduna Salman asked me: "Do you have any food?" I said: "I have found a basket." He said: "Bring it to me. If there is wealth in it, we will deposit it in the war spoils, and if there is food in it, we will eat it." We opened the basket, and in it were loaves of white flour, cheese and a knife. That was the first time the Arabs saw white bread.
