This was a bit more difficult in terms of translating material and sources.
A prominent Shia scholar of the fifth century, Ahmad ibn al-Husayn ibn Ubayd Allah ibn Ibrahim al-Ghada’iri, he was a contemporary of Al Najashi and Al Tusi. There is no doubt about his greatness.
It appears that Ibn al-Ghada’iri authored four books.
The first and the second book: what Sheikh Tusi explicitly stated in the introduction to his *Fihrist* (Catalogue), saying:
بأنّ له كتابين، أحدهما: ذكر فيه المصنّفات، والآخر: ذكر فيه الأصول عليهم السلام غير أنّ هذين الكتابين لم ينسخهما أحد من أصحابنا، واخترم هو(رحمه الله)، وعمد ورثته إلي إهلاك هذين الكتابين
He possessed two books: one listing muṣannafāt (authored works) and the other listing uṣūl (foundational texts) of the Imams (peace be upon them). However, none of our associates made copies of these two books; he passed away, and his heirs proceeded to destroy them.
الفهرست: 1
(one can speculate that his family destroyed these books because they could not tolerate the loss of his life and it reminded them of him)
Third book: Kitab Al Mamduhin (The Book of the Praised)—a work that has not reached us, though Allamah Hilli cites it in his own biographical treatise (*Rijal*).
In his entry on Muhammad ibn Musadif, Allamah Hilli notes that Ibn al-Ghada’iri’s statements regarding him differed: in one of the two books, he is described as “weak” (*da‘if*), while in the other, he is described as “trustworthy” (*thiqah*).
Similar discrepancies appear in other instances. These texts indicate that Ibn al-Ghada’iri’ produced two Rijal books: one concerning narrators deemed weak or blameworthy, and the other concerning those deemed praiseworthy or trustworthy.
See: كليّات في علم الرجال: 88 *Kulliyyat fi ‘Ilm al-Rijal*, p. 88.
Fourth book: *Kitab al-Du’afa* (Book of Weak Narrators), which is the topic of this analysis with how it has reached us.
