Ibn Saad

Ibn Sa'd (168–230 AH / 784–845 CE) was an Iraqi hadith scholar, biographer, and historian based in Baghdad, best known as the author of the early biographical encyclopedia al-Tabaqat al-Kubra ("The Great Classes") al-Hadith wal-Muhaddithun+1.

Lineage and Early Life

His full name was Abu Abd Allah Muhammad ibn Sa'd ibn Mani' al-Hadith wal-Muhaddithun+1. He was associated through clientage (wala') with Banu Hashim as a client of al-Husayn ibn Abd Allah ibn Ubayd Allah ibn al-Abbas, though some sources describe him or his family as holding clientage to Banu Zuhra or ascribe to him Zuhri descent al-Tabaqat al-Kubra - Mut…+1. He was born in Basra in 168 AH (a report places his birth broadly after 160 AH) and grew up there during an era of vibrant scholarly activity Marwiyyat al-Imam al-Zuhr…+1.

Education and Scholarly Career

Ibn Sa'd began his studies in Basra under local traditionalists such as Ismail ibn Ulayyah, Affan ibn Muslim, and Abu al-Walid al-Tayalisi al-Tabaqat al-Kubra - Mut…+1. He traveled to Kufa, Mecca, and Medina—visiting Medina prior to 200 AH to study under figures such as Ma'n ibn Isa—and eventually settled in Baghdad al-Tabaqat al-Kubra - Mut…. There he attached himself closely to the historian and jurist al-Waqidi, transcribing his books and narrations over an extended period, which earned him the lasting epithet Katib al-Waqidi ("al-Waqidi's scribe") Wafayat al-Ayan+1. Beyond al-Waqidi, he transmitted from numerous prominent authorities across Iraq and the Hijaz, including Sufyan ibn Uyaynah, Yazid ibn Harun, Abu Nu'aym al-Fadl ibn Dukayn, and Ubayd Allah ibn Musa al-Hadith wal-Muhaddithun+1.

A significant circle of scholars transmitted from Ibn Sa'd. His principal transmitters included al-Husayn ibn Muhammad ibn Fahm and al-Harith ibn Abi Usamah, both of whom preserved and transmitted al-Tabaqat al-Kubra, as well as Ibn Abi al-Dunya, the historian al-Baladhuri, Ahmad ibn Ubayd ibn Nasih, and Mus'ab al-Zubayri al-Hadith wal-Muhaddithun+1.

The Inquisition (Mihna)

In 218 AH, during the caliphate of al-Ma'mun, the Abbasid state instituted the Mihna regarding the doctrine of the createdness of the Quran al-Kamil fi al-Tarikh. The caliph ordered his deputy in Baghdad, Ishaq ibn Ibrahim, to summon and interrogate seven leading scholars, among whom was Ibn Sa'd alongside Yahya ibn Ma'in, Abu Khaythama Zuhayr ibn Harb, Abu Muslim (the dictation assistant of Yazid ibn Harun), Ismail ibn Dawud, Ismail ibn Abi Mas'ud, and Ahmad ibn al-Dawraqi al-Kamil fi al-Tarikh+1. The group was dispatched to al-Ma'mun at Raqqa, where they assented under duress and fear of execution to the assertion that the Quran was created al-Kamil fi al-Tarikh+1. They were subsequently returned to Baghdad, where their assent was made public before an assembly of jurists and hadith scholars before they were released al-Kamil fi al-Tarikh+1.

Scholarly Standing

Hadith critics and biographical authorities widely regarded Ibn Sa'd as trustworthy (thiqa), truthful (saduq), and careful in his transmissions Wafayat al-Ayan+1. Abu Hatim al-Razi stated that he was truthful, noting that he witnessed him questioning and recording hadith from al-Qawariri al-Tabaqat al-Kubra - Mut…+1. Al-Khatib al-Baghdadi affirmed his probity (‘adala) and meticulousness; addressing a report wherein Yahya ibn Ma'in purportedly accused Ibn Sa'd of falsehood, al-Khatib explained that Ibn Ma'in likely rejected an uncorroborated report originating from al-Waqidi rather than questioning Ibn Sa'd's personal integrity Wafayat al-Ayan+1. Ahmad ibn Hanbal regularly dispatched his nephew Hanbal ibn Ishaq every Friday to borrow two fascicles of al-Waqidi's material from Ibn Sa'd for study Tahdhib al-Tahdhib+1.

His reputation rests primarily on al-Tabaqat al-Kubra, one of the earliest comprehensive biographical dictionaries organized by generational classes (tabaqat) and geographical regions, alongside a shorter biographical compendium, al-Tabaqat al-Sughra al-Durr al-Thamin fi Asma…+1.

Death

Ibn Sa'd died in Baghdad on Sunday, 4 Jumada al-Akhirah 230 AH (845 CE), at the age of 62 (a variant report gives 72) al-Durr al-Thamin fi Asma…+1. Variant death dates of 236 AH and 222 AH appear in isolated accounts, but 230 AH is the consensus recorded by his direct transmitters al-Tabaqat al-Kubra. He was buried in the cemetery at Bab al-Sham in Baghdad al-Durr al-Thamin fi Asma…+1.
