A man who buys an animal, travels on it, then finds a defect in it

It is narrated from Ibn Sirin that a man bought an animal from another man and then travelled on it. When he returned, he found a defect in it. He took the dispute to Shurayh, who said: "You gave him permission to ride it."

Al-Hakam said concerning a man who bought an animal, then made it lean, and then found a defect in it: He is to return it, and he is also to pay back the difference between the prices of a fat animal and a lean one.
