Sa‘īd ibn Jubayr (665–714) (Arabic: سعيد بن جبير), also known as Abū ‘Abd Allāh, was originally from Kufa, in modern-day Iraq.
Sa'īd is held in the highest esteem by scholars of the Shi'a and Sunni Islamic tradition and was considered one of the leading jurists of the time.
At the battle of Jamājim in 82 AH (699-701), Ibn al-Ash'ath and his followers, including 100,000 from amongst the mawāli, took on the army of al-Hajjāj (d. 714), the governor of the Iraqi provinces during the reign of the Umayyad caliph Abd al-Malik.
He persisted in travelling to Mecca itself twice a year to perform the hajj and `umrah and would enter Kufa secretly to help resolve peoples' religious issues.
Sa'id was asked by Abd al-Malik ibn Marwan to write a book concerning Quranic exegesis.
