Is it obligatory to pay compensation for damages caused to the neighbor's pharmacy due to water leakage from the defendant's apartment by unintentional means, knowing that the plumber was at fault, and does the difference in claiming compensation between the pharmacy owner and his son affect the obligation to pay compensation?

Whoever damages something is responsible for guaranteeing it, whether intentionally or by mistake. However, there is no sin upon the one who makes a mistake. The plumber is responsible for guaranteeing what was damaged due to his negligence and carelessness, such as forgetting to close the main water line, for responsibility is not waived by forgetfulness. Therefore, the plumber is responsible for guaranteeing the damage to the laptop, by purchasing similar damaged parts or paying their value after assessment by experts.
