What is the ruling on the continued deposit of my salary into my bank account during my period of leave for study and work, especially since I stopped studying but did not inform my employer, and then it continued to be deposited during the war, when I, like other employees, was confined to my home? And what should I do with the salaries I have received?

The salary that was deposited into the account after discontinuing studies is not permissible to take unless authorized by the employer. If they authorize it, then it is permissible; otherwise, it must be returned to them, based on the Almighty's saying: "O you who have believed, fulfill [all] contracts," and the Prophet's (peace be upon him) saying: "Muslims are bound by their conditions."
