What is the ruling on the Jaljalutiyyah supplication (du'a') which includes words such as: "By Āj and Māhūj" and "By Āj Ayūj Jaljalayūt halhalat," and do these words contain shirk (polytheism) or a violation of Islamic law?

It is not permissible to supplicate to Allah or seek intercession with Him using names of unknown meaning or names not proven to be among the Beautiful Names of Allah, as Allah the Almighty says: (And to Allah belong the best names, so invoke Him by them). Ibn Taymiyyah emphasized that these non-Arabic terms, such as "Ya Azran" and "Ya Kiyan," were not transmitted from the Salaf, and they are meaningless in Arabic. Supplications that include strange names like "Aj" and "Mahuj" are claimed by Sufis to be names of Allah in Syriac, but this is misguidance and atheism. They might even be names of devils used in magic, which falls within the litanies (awrad) of Sufi orders like the "Khalwatiyyah" and "Awniyyah," where the murid (disciple) receives teachings of magic under the guise of divine inspirations. Scholars have mentioned that the Syriac language is collectively adopted by Sufis either to deceive people or because it was the language of pagan peoples renowned for worshipping jinn and idols. Therefore, one must be cautious of Sufi litanies that contain these unknown names.
