Musannaf Ibn Abi Shaybah 26006 — Cheese and eating it

It is narrated from Suwayd, who was a slave of Sayyiduna Salman (may Allah be pleased with him), and whom (the narrator) praised well, that he said: When we conquered al-Mada'in, the people went out in pursuit of the enemy. Meanwhile we found a basket. On seeing it, Sayyiduna Salman (may Allah be pleased with him) said: Open it. If it is food, we will eat it, and if it is property, we will hand it over to these people. When we opened it, there were some loaves of a special kind (huwwari), cheese and a knife in it. This was the first time the Arabs had seen such a thing. Sayyiduna Salman (may Allah be pleased with him) told the people how it is made. Then he cut it with the knife and said: In the name of Allah, eat.
