'Abd Al-Qahir Al-Baghdadi

Abū Manṣūr ʿAbd al-Qāhir ibn Ṭāhir bin Muḥammad bin ʿAbd Allāh al-Tamīmī al-Shāfiʿī al-Baghdādī (), more commonly known as Abd al-Qāhir al-Baghdādī () or simply Abū Manṣūr al-Baghdādī () was an Arab Sunni scholar from Baghdad. He was considered a leading Ash'arite theologian and Shafi'i jurist. He was an accomplished legal theoretician, man of letters, poet, prosodist, grammarian, heresiologist and mathematician.

Life

'Abd al-Qahir al-Baghdadi was born and raised in Baghdad. He was a member of the Arab tribe of Banu Tamim. Ibn 'Asakir writes that Abu Mansur met the students of the companions of Imam al-Ashari and acquired knowledge from them. Among the Ashari imams of the third generation, he is the senior of al-Bayhaqi and the identical contemporary of Abu Dharr al-Harawi and Abu Muhammad al-Juwayni. Abu Mansur was brought in his youth by his father from Baghdad to Nishapur. In his new city is where he found his education. Abu Mansur was known as a wealthy man where he donated his whole fortune to the scholars of wisdom until he was qualified to instruct in seventeen various subjects, including fiqh, usul, arithmetic, law of inheritance and theology. Most of the scholars of Khurasan were his pupils. He was a senior pupil of Abu Ishaq al-Isfarayini, and he and Abu Sahl al-Su'luki steadfastly upheld the al-Shafi`i view that "the Book cannot be abrogated by the Sunna." In the mosque of `Aqil, Abu Mansur took over as headmaster from Abu Ishaq al-Isfarayini, and it was under his tutelage that al-Bayhaqi, al-Qushayri, Abu Khalaf al-Tabari, and Nasir al-Marwazi learned. He studied Hadith under Abu Bakr al-Isma'ili and others. Due to Turkmen riots near the end of his life, Abu Mansur was forced to flee from Nishapur and established himself as a venerable citizen of Isfayayin, where he died in 449/1038. He was buried right next to his teacher Abu Ishaq al-Isfarayini.

Reception

Abu Uthman al-Sabuni highly praised him and said: “one of the imams of the principles of the Religion and foremost authorities of Islam by consensus of its most eminent and competent scholars.”
