Musannaf Ibn Abi Shaybah

It is narrated from Muhammad that a man bargained with another man over the price of a cloth. That man said, "I will sell you a cloth like this for such and such price." Then he made a sale with him and went to the cloth seller, bought the cloth from him, and when he returned, the buyer refused to take the cloth. They took their dispute to Hazrat Shurayh. Hazrat Shurayh said: "We do not find anything more similar to this than its likeness," and then he enforced the sale upon him.
