Khalaf- Khalaf is the name of the tenth and final authentic (mutawaatir) way of recitation

Khalaf is Khalaf Abu Muhammed bin Hishaam bin Tha'lab Al-Bazzar Al-Baghdadi.  هو خلف أبو محمد خلف بن هشام بن ثعلب البزار He is the same Khalaf who is a raawee of the recitation of Hamzah.  He was born 150 h and memorized the Qur'an at the young age of 10 years old.  He started being a student of scholars of recitation when he was 13 years old. He was a very trustworthy, ascetic, knowledgeable servant.  It was said he had trouble learning a chapter of grammar so he gave in charity 80,000 dirham until he memorized it. He disliked being called Al-Bazzaar and said call me Al-Muqri (reciter).   He took his recitation by presenting the complete Qur'an to Sulaim bin 'Eesaa and Abdualrahma bin Abee Hammaad who both learned directly and recited from Hamzah.

The way of recitation of Khalaf has two raawee:

Is-haaq He is Ishaaq bin Ibrahim bin 'Uthmaan bin Abdullah Al-Maruzee then Al-Baghdaadi. هو إسحاق بن إبراهيم بن عثمان بن عبد الله المروزي ثم البغادي He died 280 h.

Idrees He is Idrees bin Abdul-Kareem Al-Baghdaadi Al-Hadaad.  He died on the day of Al-Adhha 292h
