Am I obligated to seek personal absolution from the shop owner, or is it sufficient to alert my friend that he must compensate or seek absolution from the shop owner, knowing that I was a passenger and not the driver?

If a person is riding their animal or driving their car in a normal manner and runs over a small pebble that damages something, there is no liability on them, because they are authorized to travel, and it is impossible for them to guard against such an occurrence. Therefore, what results from an authorized act is not guaranteed. However, if the travel is not normal, such as driving at high speed on a gravel road, then they are liable due to their transgression. Jurists have stipulated that if a pebble flies off a animal's hoof during its normal gait, there is no liability, unless it was large, or resulted from the animal kicking it forcefully, or if the travel was reckless. Accordingly, the car owner is not liable for damage caused if they were driving within the permitted speed limit and the road conditions did not necessitate slowing down; otherwise, they are liable, and the liability falls solely upon them.
