[1] Alongside Qalun, he was one of the two primary transmitters of the canonical reading method of Nafi‘ al-Madani.
[1][2][3] Together, their style is the most common form of Qur'anic recitation in the generality of African mosques outside of Egypt,[4] and is also popular in Yemen[5] and Darfur despite the rest of Sudan following the method of Hafs.
[9] It is attributed to Imam Warsh who in turn got it from his teacher Nafi‘ al-Madani who was one of the transmitters of the seven recitations.
Imam Warsh (110-197AH) was born Uthman Ibn Sa‘id al-Qutbi in Egypt.
[11] In the 10th century, the Muslim scholar Ibn Mujāhid canonized the seven readings of the Quran including Warsh 'an Naafi'.
