The Quran in the Ishaq al-Warraq ‘an Khalaf riwaya

Ishaq al-Warraq ‘an Khalaf is one of the two transmissions of the personal reading of Khalaf ibn Hisham al-Bazzar, the tenth of the ten canonical readers. Its transmitter, Abu Ya‘qub Ishaq ibn Ibrahim ibn ‘Uthman al-Marwazi, who settled in Baghdad and was known as "Khalaf's copyist" (warraq), died in 899 (286 AH); he reportedly knew no other reading. Today it is mainly preserved in the teaching of the ten readings.

Khalaf (767–844; 150–229 AH), a leading scholar of Baghdad, is also one of Hamza's two transmitters (see Khalaf ‘an Hamza). He had read with Sulaym, Hamza's student, and with other Kufan masters, notably for the reading of ‘Asim, and then composed his own selection (ikhtiyar), which Ibn al-Jazari describes in his Durra with Hamza's reading as its base. Ishaq read this selection with him and taught it after his death; when he became hard of hearing, his son Muhammad took over.

Khalaf reads Māliki yawmi d-dīn with a long alif, joins the surahs without a basmala, gives the madd a medium length and applies full imala to words such as al-hudā, as well as to jā’a and shā’a. Unlike Hamza, he makes no short pause (sakt) before a hamza, and he fully pronounces two consecutive hamzas, for example in a’a‘jamiyyun (41:44), where Hafs eases the second. According to the Durra, Ishaq and Idris al-Haddad agree on all the general rules.

Reciters who have recorded it include Yousef Bin Noah Ahmad and Ahmed Aissa El Masarawi.
