"Zakaria ibn Idris Ash'ari Qomi", in addition to training outstanding and powerful students, also wrote books. Shaykh Tusi[12] and Najashi[2] have listed only one book in his name, and Agha Bozorg Tehrani has mentioned it in "Az-Zaree'a" under the title "Kitab al-Hadith" (Arabic: کتاب الحدیث).[13][14]
