Background |
Abū Manṣūr ʿAbd al-Qāhir ibn Ṭāhir bin Muḥammad bin ʿAbd Allāh al-Tamīmī al-Shāfiʿī al-Baghdādī ( Arabic: أبو منصور عبدالقاهر ابن طاهر بن محمد بن عبدالله التميمي الشافعي البغدادي) was an Arab [4] Shafi'i scholar, Usul Imam, heresiologist and mathematician.
'Abd al-Qahir al-Baghdadi was born and raised in Baghdad. [5] He was a member of the Arab tribe of Banu Tamim. [4] He received his education in Nishabur and subsequently taught 17 subjects, including law, usul, arithmetic, law of inheritance and theology. [1] Most of the scholars of Khurasan were his pupils. [1] Ibn 'Asakir writes that Abu Mansur met the companions of the companions of Imam al-Ashari and acquired knowledge from them. [6]
'Abd al-Qahir al-Baghdadi wrote several books including Kitāb Uṣūl al-Dīn, a systematic treatise, beginning with the nature of knowledge, creation, how the Creator is known, His attributes, etc.... and Al-Farq bayn al-Firaq which takes each sect separately, judges all from the standpoint of orthodoxy and condemns all which deviate from the straight path. [1] Both books were major works on the beliefs of Ahl al-Sunna. [5]
He also wrote the treatise al-Takmila fi'l-Hisab which contains results in number theory, and comments on works by al-Khwarizmi which are now lost.
