Waki ibn al-Jarrah

Abū Sufyān Wakīʿ ibn al-Jarrāḥ ibn Malīḥ al-Ruʾāsī al-Kilābī al-Kufī (745/47–812) was among the most prominent hadith scholar of his time. He was based in his hometown of Kufa and was one of the principal teachers of the major Sunni Muslim jurists, Ahmad ibn Hanbal.
Origins.
Waki was born in Kufa, or in the village of Ustuwa near Nishapur, in 128/129 AH (745–747 CE). His father al-Jarrah ibn Malih belonged to the Ubayd ibn Ru'as clan of the Banu Kilab tribe and was born in Soghdia, while his mother, a daughter of Amra ibn Shaddad ibn Thawr of the same clan, was born in Bukhara; the Ubayd ibn Ru'as had been settled in Kufa following the Muslim conquest of Iraq in the 630s. The family was well off and al-Jarrah was the supervisor of the "bayt al-darb" (mint) at Rayy, before being appointed head of the "bayt al-mal" (treasury) in Baghdad under the Abbasid caliph Harun al-Rashid ().
Career.
Schooled in the Islamic religious sciences, especially the hadith (traditions attributed to the Islamic prophet Muhammad), Waki became a leading traditionist ("muhaddith") in his hometown, known for transmitting numerous "hadiths" based on his memorizations. Despite the errors of transmission attributed to him, Waki was generally regarded as the best "muhaddith" of his time. His refusal of an appointment as qadi (head judge) by Harun al-Rashid out of concern of dependence on the state further contributed to his reputation for piety and ascetism.
Ibn Hajar al-Asqalani has mentioned a long list of his teachers and students in his work "Tahdhib al-tahdhib". He transmitted "hadiths" on the authority of the earlier Muslim scholars Isma'il ibn Abi Khalid, Ikrima ibn Ammar, al-Awza'i, al-Amash, and Malik ibn Anas, as well as his father. Al-Dhahabi in his "Siyar a`lam al-nubala" has listed the names of about 20 teachers of Waki out of which the best known were Sufyan al-Thawri, Shu'ba ibn al-Ḥajjāj and Ibn Jurayj. He was among the most important teachers of Ahmad ibn Hanbal, founder and namesake of the Hanbali school of Sunni Muslim jurisprudence ("fiqh"). Waki himself was classified as a follower of the Hanafi "fiqh" of Sunni Islam.
Waki built a mosque in Kufa, installing as its imam a tribesman of his, Humayd ibn Abd al-Rahman ibn Humayd al-Ru'asi.
Death and descendants.
On his return from the Hajj (pilgrimage to Mecca), Waki died in the Fayd oasis in 197 AH (812). His son Sufyan was also a Kufan traditionist, though of poor reputation. Sufyan died at an old age in 861.
Literary works.
Although Waki was popularly held to have never possessed a book, he authored a number of works:
