We have narrated from Qadi Shurayh (may Allah have mercy on him) that he said: "There is no liability (compensation) on one who hires (an animal)."
Then if he transgresses and exceeds the agreed time, and it (the animal) perishes, Shurayh (may Allah have mercy on him) said: "Both the rent and the liability (compensation) will be combined upon him."
