al-Tabaqat al-Kubra

al-Tabaqat al-Kubra (Arabic: الطبقات الكبرى, The Great Book of Generations), also referred to as al-Tabaqat al-Kabir, is a biographical and historical work composed by the Baghdadi scholar and traditionist Ibn Saad (168–230 AH / 784–845 CE) Marwiyyat al-Imam al-Zuhr…+1. It is one of the earliest surviving biographical dictionaries in Islamic literature, covering the prophetic biography (sirah), the military expeditions (maghazi), and the biographical records of the Prophet's Companions, Successors (tabi'un), and subsequent generations down to the author's era Marwiyyat al-Imam al-Zuhr…+1.

Structure and Organization

The work combines chronological and geographic classification systems Ulum al-Hadith wa Mustala…:

• Prophetic Biography and Campaigns: The opening section begins with the lineages of the earlier prophets and the ancestors of Muhammad ﷺ, followed by his life in Mecca, the migration (hijra), his letters to regional rulers, and the arriving tribal delegations Marwiyyat al-Imam al-Zuhr…+1. This is followed by accounts of the Prophet's military expeditions and detachments, his final illness, death, estate, elegies, and the jurists who gave legal verdicts in Medina during his lifetime al-Tabaqat al-Kubra+1.
• The Companions: Arranged primarily by priority in embracing Islam and participation in key historical milestones Ulum al-Hadith wa Mustala…+1. The categories begin with the participants of the Battle of Badr from among the Muhajirun and the Ansar, followed by early converts who did not attend Badr but migrated to Abyssinia or fought at the Battle of Uhud, those who fought at the Battle of the Trench, and those who accepted Islam prior to the conquest of Mecca Mawsuat Safir lil-Tarikh …+1.
• The Successors and Later Generations: Classified geographically by regional center (misr), including Medina, Mecca, al-Ta'if, Yemen, al-Yamama, al-Bahrayn, Kufa, Basra, Damascus and the wider Syrian region, al-Jazira, Egypt, al-Andalus, Wasit, al-Mada'in, Baghdad, Khurasan, Rayy, Hamadhan, Qum, and al-Anbar al-Hadith wal-Muhaddithun+1. Within each regional division, entries are organized by successive generational classes (tabaqat) spanning approximately twenty years each Ulum al-Hadith wa Mustala….
• Women: The final volume is dedicated exclusively to female Companions and notable women of later generations Akhbar Qabail al-Khazraj+1.

Method and Sources

In his biographical entries, Ibn Sa'd routinely documents each subject's paternal and maternal lineage, children, wives, kunyas, physical descriptions, dyeing of hair and beard, ring inscriptions, occupations, administrative and judicial appointments, and reliability in hadith transmission Asr al-Khilafa al-Rashida…+1.

He gathered his material through direct oral transmission and written records from more than sixty teachers Marwiyyat al-Imam al-Zuhr…+1. Prominent among his authorities were al-Waqidi, Abu Nu'aym al-Fadl ibn Dukayn, Affan ibn Muslim, Ubayd Allah ibn Musa, Sufyan ibn Uyayna, Man ibn Isa, and Hisham ibn al-Kalbi for pre-Islamic genealogy Awail al-Muallifin fi al-…+1. In compiling the maghazi, he frequently used combined chains of transmission (isnad jam'i), introducing composite reports with phrases such as "the report of one entered into that of another" (دخل حديث بعضهم في حديث بعض) before supplementing them with individual isolated transmissions Ilm al-Rijal Nashatuhu wa….

Transmission and Additions

The book was transmitted from Ibn Sa'd primarily by his students al-Harith ibn Muhammad ibn Abi Usama and al-Husayn ibn Muhammad ibn Fahm Ulum al-Hadith wa Mustala…+1. Later scholars noted that certain biographical notices containing death dates occurring after Ibn Sa'd's demise in 230 AH—such as Ibn Sa'd's own biographical sketch—were editorial additions incorporated by his transmitters, notably Ibn Fahm al-Tabaqat al-Kubra - Mut…+1.

Reception and Scholarly Standing

al-Tabaqat al-Kubra was praised by early and later critics as a fundamental reference for hadith critics, jurists, and historians al-Hadith wal-Muhaddithun. Al-Khatib al-Baghdadi noted that Ibn Sa'd authored a vast work on the generations of the Companions, the Successors, and those who followed, excelling in its execution, and he cited it over 250 times in Tarikh Baghdad Marwiyyat al-Imam al-Zuhr…+1. Al-Dhahabi remarked that Ibn Sa'd was a vessel of knowledge and that whoever examines his Tabaqat yields to his erudition Marwiyyat al-Imam al-Zuhr…. Al-Nawawi affirmed relying on it in Tahdhib al-Asma wal-Lughat as an authoritative source al-Tabaqat al-Kubra. The text served as a primary foundation for subsequent biographical works, including Ibn Asakir's Tarikh Dimashq, al-Dhahabi's Siyar A'lam al-Nubala, and Ibn Hajar al-Asqalani's al-Isabah fi Tamyiz al-Sahabah and Tahdhib al-Tahdhib al-Tabaqat al-Kubra.

While hadith critics recognized Ibn Sa'd as trustworthy and scrupulous (thiqah saduq), some expressed reservations regarding his reliance on narrators considered weak in hadith transmission, particularly al-Waqidi and Hisham ibn al-Kalbi, as well as the presence of disconnected (maqtu) and hurried (mursal) chains in his historical compilations al-Hadith wal-Muhaddithun+1.

Print History and Supplements

The text was edited under the supervision of Eduard Sachau alongside a team of orientalists and published in Leiden between 1904 and 1918 in eight volumes, followed by indices in three parts completed between 1920 and 1940 al-Tabaqat al-Kubra. This edition was later reproduced in Beirut and Cairo al-Tabaqat al-Kubra - Mut…+1. Because several manuscripts used in early printings had lacunae—such as portions of the later classes of the Companions and Medina Successors—supplementary manuscripts were later identified and published in separate volumes, such as the fifth class of the Companions and the supplementary generations of the Successors (Mutammim al-Tabi'in) al-Tabaqat al-Kubra - Mut…+2.
