What is the ruling on the Salah of Al-Fatih (Al-Fatih Prayer), which is common in the Maghreb countries, and is there anything in it that contradicts Islamic law?

This ذكر (remembrance/litany) is an innovation (bid‘ah) and contrary to Islamic law for two reasons: performing this act of worship in this specific manner while preferring it over other wirds (litanies) and reciting the Quran. The fundamental principle is that Allah should not be worshipped except in the way He has prescribed. Additionally, some of its phrases contain ambiguity that could carry false meanings, such as "the opener of what was closed." A Muslim should engage in the prescribed litanies and supplications. Those who recite them out of ignorance are excused, and they should be taught the legitimate form of sending blessings upon the Prophet, peace and blessings be upon him.
