Abu Mansur 'Abd al-Qahir ibn Tahir al-Baghdadi (Arabic: أبو منصور عبدالقاهر ابن طاهر بن محمد بن عبدالله التميمي الشافعي البغدادي) was a Shafi'i scholar, Imam in fundamentals of Islam (Usul), heresiologist and mathematician.
Early life and education
'Abd al-Qahir al-Baghdadi was born and raised in Baghdad.[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.[5]
Works
'Abd al-Qahir al-Baghdadi wrote several books including Usul al-Din, 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.[4]
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.
