What is the nature of «إِيَّاكُمْ وَالْمُغِيرَةَ بْنَ سَعِيدٍ»?

Narrator Criticism: Al-Mughīrah b. Saʿīd, Shaqīq and Jābir al-Juʿfī

• Muslim’s own criticism, without a separate chain
• A transmitted severe warning of Ibrāhīm al-Nakhaʿī
• An untransmitted personal ruling of Ibn Mahdī
• Ibn ʿAwn’s own judgment, with no reported statement by Ibrāhīm
