Early life and education
'Abd al-Qahir al-Baghdadi was born and raised in Baghdad. He received his education in Nishabur and subsequently taught 17 subjects, including law, usul, arithmetic, law of inheritance and theology. Most of the scholars of Khurasan were his pupils. Ibn 'Asakir writes that Abu Mansur met the companions of the companions of Imam al-Ashari and acquired knowledge from them.
'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. Both books were major works on the beliefs of Ahl al-Sunna.
