Gualtherüs (Gautier) Hendrik Albert Juynboll[1] (1935–2010) was a scholar of Islam specializing in hadith (the collection of sayings attributed to the Prophet of Islam Muhammad),[2] about which he published more than twenty articles.
[6] Juynboll was born in Leiden, Netherlands in 1935[citation needed] and was from a "prominent" family of Orientalists.
[2] He studied Arabic and Islam at Leiden University and obtained his doctoral degree in 1969.
[2] He is noted for the contention that isnads (the chains of oral transmission of hadith) "tell us important things about the story to which the isnäd is attached".
