Qira'at al-'Ashr
The ten readings established by mass transmission, each named after the Imam known for it.
The Qur'an was received and passed on in more than one recognised reading. Ten of these are established as mutawatir — transmitted in every generation by so many that agreement on an error is not possible.
Each is named after the Imam who became known for it: Nafi' al-Madani, Ibn Kathir al-Makki, Abu 'Amr al-Basri, Ibn 'Amir al-Shami, 'Asim al-Kufi, Hamzah al-Kufi and al-Kisa'i al-Kufi — the seven gathered by Ibn Mujahid — with Abu Ja'far al-Madani, Ya'qub al-Hadrami and Khalaf al-'Ashir completing the ten.
The differences between them touch pronunciation, vowelling and occasionally a word. None contradicts another: taken together they show how the Qur’an was actually received, not competing versions of it.
