Musannaf Ibn Abi Shaybah 22347 — The fuller, the dyer and others

Al-A'mash (may Allah have mercy on him) said: My neighbour Thabit, who was a fuller, told me to ask Ibrahim (may Allah have mercy on him) about a man who gave his slave some clothes, and they were lost: what is the ruling? I asked Ibrahim, and he said: Did he not know that he was his slave? I said: Yes. He said: He is liable.
