Is it permissible for an employee to curse his manager if the manager denies him his rights and transgresses against him?

Question:
May Allah reward you, our Shaykh. This questioner says: If my manager at work transgresses against me and deprives me of my right, preventing me from some of what I am entitled to, such as a promotion and other things, am I allowed to curse him?

Answer:
By Allah, this is a matter of administrative procedure. If you curse him, Allah knows best what is upon you. You should review the matter with the competent authority above this manager. If you are entitled to something and this manager has deprived you of your right, you must complain to the authority above him so that they can give you your rights against this manager. Do not use cursing. Yes.
