Abu Ishaq al-Zajjaj
Grammarian of Basrah

Abū Isḥāq Ibrāhīm ibn Muḥammad ibn al-Sarī al-Zajjāj (Arabic: أبو إسحاق إبراهيم بن محمد بن السري الزجاج) was a grammarian of Basrah, a scholar of philology and theology and a favourite at the Abbāsid court. He died in 922 at Baghdād, the capital city in his time.
Life
Abū Isḥāq Ibrāhīm ibn Muḥammad al-Sarī (Surrī) al-Zajjāj had been a glass-grinder – al-Zajjāj means 'the glassman' – before abandoning this trade to study philology under the two leading grammarians, al-Mubarrad of the Baṣran school and Tha'lab of the Kufan school. As top student and class representative he advised al-Mubarrad. He studied "Al-Kitāb" of Sībawayh with the Baṣrah grammarian Abū Fahd.
Al-Zajjāj entered the Abbāsid court, first as tutor to al-Qāsim ibn ‘Ubayd Allāh, son of the vizier ‘Ubayd Allāh ibn Sulaymān ibn Wahb’s and later, as tutor to the sons of the caliph al-Mu‘taḍid.
On his succession to the vizierate, Caliph al-Mu’taḍid ordered vizier al-Qāsim to commission an exposition of the Compendium of Speech by Maḥbarah al-Nadīm. Both Tha’lab and Al-Mubarrad declined the project for lack of knowledge and old age respectively. Al-Mubarrad proposed his friend and relative novice al-Zajjāj, who was commissioned to work on just two sections as a trial of his abilities. In doing his research he consulted books on language by Tha‘lab, al-Sukkarī, et al.

Why this record matters
The phrase “grammarian of Basrah” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 28, 2026. The linked authority identifier is Q12177686. VIAF identifies the subject as 79203667. The Library of Congress control number is n84044182. 3 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
