Abu Muhammad Khalaf ibn Hisham ibn Tha'lab al-Asadi al-Bazzar al-Baghdadi, better known as Khalaf (150–229AH, -844CE),[1] was an important figure in the history of the Qur'an and the Qira'at, or method of recitation. In addition to being a transmitter for the Quran reading method of Hamzah az-Zaiyyat,[2][3] one of the seven canonical readers, he was also known for his own independent method that is counted among the three accepted but less famous methods.[3]
For Khalaf's own, independent method of recitation, the two primary transmitters from him were Ishaq al-Maruzi and Idris al-Haddad.[4]
