Abu Bakr Ibn Mujāhid
Abū Bakr Ibn Mujāhid was a scholar of Islamic studies. He studied Qur'ān and Hadith in Baghdad. He was most notable for establishing the seven canonical Qur'anic readings. His list of the seven canonical readings was made up of reciters from the cities of Mecca, Madinah, Kufah, Basra and Damascus. He was also notable for delivering the charge of heretical Qur'anic exegesis that reopened the trial of Mansur al-Hallaj, and ultimately led to his execution by the Abbasid Caliphate al-Muqtadir.
In addition to having established and delineated the canonical readings, Ibn Mujahid was also a student of Qunbul, one of the canonical readers.
