Abū l-Qāsim Saʿd b. ʿAbd Allāh al-Ashʿarī al-Qummī (Arabic: ابوالقاسم سعد بن عبدالله الاشعري القمي) was a Shi'a muhaddith in the 3rd/9th century. He lived in Baghdad for a while, but his permanent residence was probably in Qom. Sa'd al-Ash'ari lived in the period of the imamate of Imam Hasan al-'Askari (a) and the Minor Occultation of Imam al-Mahdi (a).
Sa'd b. 'Abd Allah had many teachers, including:
- Abu 'Ali Hasan b. 'Arafa al-'Abdi al-Baghdadi: a scholar of Arabic literature, hadiths, and the author of some works in hadiths and other fields, including the book, al-Juz' . He died in 257/870 in Samarra.
- Abu Ja'far Muhammad b. 'Abd al-Malik al-Daqiqi al-Wasiti (d. 266/879): he lived in Baghdad.
- Abu Hatam Muhammad b. Idris al-Razi (d. 277/890): he wrote works concerning the exegesis of the Quran and fiqh.
- Abu Muqatil al-Sayl al-Daylami (the head of Rey): he transmitted hadiths from Imam al-Hadi (a) and was the author of the book, al-Ihtijaj fi l-imama containing hadiths and debates about kalam.
- Abu Muqatil al-Darir: he was a prominent poet of his time. He composed the well-known qasida of Rey about Hasan b. Zayd who led an uprising in Tabaristan and took over the government.
- Ahmad b. Muhammad b. Khalid al-Barqi
- 'Ali b. Mahziyar al-Ahwazi
- Ibrahim b. Mahziyar

Some of his students are as follow:
- Ibn Babawayh, father of al-Shaykh al-Saduq
- Ibn Qulawayh al-Qummi, the teacher of al-Shaykh al-Mufid
- Ahmad b. Muhammad b. Yahya al-'Attar
- Abu Ya'la Hamza b. Qasim al-'Alawi al-'Abbasi
Transmission of Hadiths
There are 1142 hadiths transmitted by Sa'd in the Four Books of Shi'as (i.e. al-Tahdhib, al-Istibsar, al-Kafi, and Man la yahduruh al-faqih). Moreover, other hadiths by him are available in Bihar al-anwar, Wasa'il al-Shi'a, Kamal al-din, and so on. The muhaddiths from whom Sa'd al-Ash'ari transmitted hadiths are over 34 people.
Sa'd b. 'Abd Allah wrote over 36 books concerning various issues (fiqh, kalam, exegesis of the Quran, rijal, and so on). A few of these works are available among collections of hadiths, including a book of his called Basa'ir al-darajat. It seems that in writing this work, he followed the lead of his contemporary scholar, Muhammad b. Hasan al-Saffar al-Qummi's book, Basa'ir al-darajat. The book is concerned with the virtues of the Imams (a). The book is not available today; what is available is a summary of it made by al-Shaykh Hasan b. Sulayman al-Hilli, a student of al-Shahid al-Awwal.
The only book of his which was published independently is al-Maqalat wa l-firaq. A manuscript of this book was recently found and was published with some addenda and commentaries. The book is concerned with various Shi'a denominations from the period of the Prophet Muhammad (s) until the author's time and criticisms of their views and arguments.
some of his works are as follow:
- Basa'ir al-darajat
- Firaq al-shi'a (al-Maqalat wa l-firaq)
- Kitab al-radd 'ala l-ghulat
- Nasikh al-Qur'an wa mansukhuh wa muhkamuh wa mutashabihuh
- Fadl al-du'a' wa l-dhikr
- Ruwat al-hadith
- Fadl al-Qom wa l-Kufa
- Fadl al-nabi
- Manaqib al-shi'a 
In order to propagate the Shi'a culture and criticize non-Shi'a schools of thoughts, Sa'd held debates. He points to such meetings when he writes:
- I had a great passion for collecting books concerning detailed issues. I was interested because I sought to learn useful knowledge and talk about complicated issues in scholarly meetings with my opponents. I completely believed in the Imamiyya. I was never concerned with my own convenience, health, and security and was mostly concerned with criticizing their views about wilaya and khilafa. I talked about the brutalities of their leaders.
Moreover, Sa'd's books concerning Shi'a denominations, heads of Shi'as, imamate, and the like are evidence for his passion for having scholarly debates and arguments.
Significance in the Transmission of Hadiths
There is a disagreement among historiographers over the year of Sa'd's death:
- Al-Najashi believes that Sa'd died in 301/913.
- Hasan b. Dawud al-Hilli takes it to be 300/912.
- Agha Buzurg Tihrani also takes it to be 300/912.
It is not known where he was buried.
