Muhammad b. Mansur al-Muradi

Salaams!

Thank you for your question! I apologise for our delay. As for the lineage of Allama Muhammad b. Mansur al-Muraadi (150-290 AH), I couldn't find much but I'll keep looking. As for his credentials, he is known as "Sheikh al-Islam" by our scholars. He was one of the most prominent hadith scholars of Kufa during his time. Even Sunni traditionalist adh-Dhahabi says of him: "Imam; hadith scholar; reliable (thiqa); scholar." He related ahadith from numerous authorities of the Ahl al-Bayt. He was also a student and companion of Imam al-Qasim ar-Rassi (as) for 25 years and transmitted ahadith and fatawa from him. He also accompanied Imams Ahmed b. Isa (as), Abdullah b. Musa (as) and Yahya b. al-Hasan (as).

He authored and compiled more than 30 books some of which include: Amali of Ahmed b. Isa (as), Kitaab adh-Dhikr, At-Tafseer Kabeer and Sagheer, Seera al-Aimma al-Adila, Al-Kitaab al-Khamees, Risaala 'ala Lisaan at-Taalibeen ila al-Hasan b. Zayd, Al-Minaahi, and others. The only extant books from him, I believe, is Amaali Ahmed b. Isa, Kitaab adh-Dhikr and Al-Minaahi.

He is who is meant when Al-Jaami al-Kaafi when it says "Muhammad says..."

And Allah knows best!
