An employer found out that his worker has been stealing money from his business for some time. though he has not caught him red handed, the overwhelming circumstantial evidences leaves no doubt at all about the theft. He is the only worker and the money gets missing only after his work. This happens for many times. There are nobody else who would have access to the money except him.Before he is hired for work no money is lost.However the worker stubbornly refused to admit his wrongdoing. The employer straightway cut the wages of the worker to cover his loss due to the theft as it would be a messy ,costly and waste of time to bring the case in the present court system. Also the court system is not based on syariah. What is the Islam ruling to the employer .Has he committed sin by doing so or he is justified to do so in the present situation especially it is not just suspicion.
