The Quran in the Idris al-Haddad ‘an Khalaf riwaya

Idris al-Haddad ‘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 al-Hasan Idris ibn ‘Abd al-Karim al-Haddad (815–905; 199–292 AH), a Baghdad reader who died on the day of Eid al-Adha aged 93, was a master renowned for his precision, to whom students travelled from afar. Today it is mainly preserved in the teaching of the ten readings.

Khalaf (767–844; 150–229 AH), a leading scholar of Baghdad and one of Hamza's two transmitters (see Khalaf ‘an Hamza), composed his own selection (ikhtiyar), which Ibn al-Jazari describes in his Durra with Hamza's reading as its base. Idris received from him both his transmission of Hamza and this selection; he also studied hadith with Ahmad ibn Hanbal and Yahya ibn Ma‘in, and al-Daraqutni called him "trustworthy, and a degree above". His students included Ibn Mujahid and Ibn Shanabudh.

Khalaf's reading has Māliki yawmi d-dīn with a long alif, surahs joined without a basmala, a medium madd, full imala in words such as al-hudā, and two consecutive hamzas fully pronounced. According to the Durra, Idris and Ishaq al-Warraq agree on all the general rules; al-Nashr notes, however, that some routes of Idris — alone among Khalaf's — make a short pause (sakt) before a hamza.

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