What is "al-buzzi"

Abu al-Hasan Ahmad Ibn Muhammad Ibn ‘Abdillah Ibn Buzzah, better known simply as al-Buzzi (170-250AH), was an important figure in the transmission of Qira'at, the seven canonical methods of Qur'an reading. He and Qunbul were the primary people responsible for spreading the recitation method of Ibn Kathir al-Makki, which became especially popular among the people of Mecca.

Al-Buzzi was considered the chief Qāriʾ in his time and was also the Mu'adhin of Al-Masjid al-Haram. He died in 864CE.
