Liability of Technician or Person with a Certain Skill

“Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin, would hold a cleaner liable as well as a dyer as precautionary measures to protect the interests of the people but my father would deal with them more graciously if they were trusted ones.’”

“Abu ‘Abd Allah (a.s.), has said that ‘Amir al-Mu’minin would hold cleaners, jewelers and dyers liable as precautionary measure to protect the interests of the people; but he would not hold them liable for things burnt or drowned. When a ship drowned with its contents and people found things thrown on shore, it was for the people of the area because of their being more rightful in the case. Whatever people found by diving and the owner had abandoned, it was considered their things.’”

“Abu ‘Abd Allah (a.s.), has said that once a man who had hired another man to mend his door and who by driving a nail into the door had damaged it, came for judgment before ’Amir al- Mu’minin, and he (’Amir al-Mu’minin) held him liable for the door.’”
