Musannaf Ibn Abi Shaybah 23305 — Sale by description

Ibrahim bin Maysarah (may Allah have mercy on him) said: I asked Tawus: A man bargained with me over merchandise that I do not have, and he says: "Buy it, and I will buy it from you." And were it not for him, I would not have bought it? Tawus disliked this sale.
