Is supplicating with "O Allah, return the magic to whoever performed it, confine it within their body, and unleash all their devils upon them," or detailing types of magic in supplication, considered an transgression in supplication because it is not from the Sunnah?

We have clarified that transgression in supplication (Du'a) refers to supplicating for something impossible or sinful, raising one's voice beyond necessity, or seeking the status of a prophet. None of these were observed in the two aforementioned supplications. There is no harm in striving in supplication and detailing it, as detailed supplications have been narrated from the Prophet, peace and blessings be upon him, and the Companions, such as the Prophet's supplication: "O Allah, forgive our living and our dead..." and Al-Hasan Al-Basri's supplication: "All praise is due to You for every blessing You have bestowed upon us..." and the supplication in the final Tashahhud: "O Allah, forgive us for what we have put forward and what we have delayed..." Among the transgressions in supplication is supplicating against an oppressor for more than the injustice they committed.
