What is the grade of the lengthy Hadith narrated on the authority of Abdullah ibn al-Mubarak from Khalid ibn Ma'dan, which states: "Indeed, Allah, the blessed and most high, created seven angels..."?

The lengthy Hadith (definition) narrated from Mu'adh (may Allah be pleased with him), which speaks of the creation of seven angels before the heavens and the earth, and the appointment of an angel as a gatekeeper for each heaven, and the ascent of the guardian angels with the servant's deeds, and the rejection of deeds due to backbiting, is an unsound Hadith; rather, it is fabricated (mawdu'). Its fabrication has been ruled upon by Ibn al-Jawzi, al-Suyuti, al-Shawkani, al-Albani, and others.
