Is it permissible to deduct a portion of a domestic worker's salary (2000 Riyals) if she refuses to complete the agreed-upon two-year period, knowing that the cost of her recruitment was (5000 Riyals) for two years and she has only worked for one year?

The basic principle concerning ijara (leasing/hiring) is that it is a binding contract for both parties, according to the majority of scholars. Neither party is permitted to annul the contract except with the consent of the other party, due to the generality of Allah's saying: (O you who have believed, fulfill [your] contracts). If an agreement has been reached with the maid for a specific contract duration, then there is no objection to deducting an amount corresponding to the remaining period of the contract if she breaches it, in order to avert harm, in accordance with the principle: "Harm is to be removed."
