َAs far as I know, there is the shrine (tomb) of a person whose name is considered as Ali-ibn-Mahziar-al-Ahvazi (علی بن مهزیار الاهوازی) in Ahvaz (Ahwaz) (the capital of Khuzestan province (Iran)). Seemingly he is as a famous Faghih (the jurist) and also a narrator of traditions. I was wondering who he was exactly and which Imam he was contemporary with.
Ali ibn Mahziar Ahvazi (علی بن مهزیار الاهوازی):
He was one of devotees (or actually companions) of Imam Mohammad al Taqi (Javad) (p.b.u.h.), Imam Hadi and Imam Hasan Askari (peace be upon them)...
Ali ebne mahziar ahvazi (the 9th century ) was famous shiah religious jurisprudent , religious narrator and savant , he was one of devotees of Imam Javad (p.b.u.h.) , Imam Hadi (p.b.u.h.) And Imam Hasn Askari (p.b.u.h.) and learned Islamic jurisprudences of them and in some areas especially Ahvaz he was their agent , shiah savants accepted his religious narrates about holy Imams (p.b.u.h.) with complete confidence .
Ali ebne mahziar was of Doraq (Shadegan) people ,later he resided in Ahvaz . nevertheless he was born in Hendijan ( hendian) but because Hendijan was Doraq city subarea he was introduced as Doraq resident . his father was Christian But at adolescence along with his father turned into Muslim . according with some stories he died at Imam Hasn Askari (p.b.u.h.) time . according with historical narratives , when Abasi caliph mamoon commanded to transfer Imam Reza ( p.b.u.h.) to Khorasn from Madineh, The Imam entered Ahvaz at year 822 and stayed at this city , few days , after that on Imam ( p.b.u.h.) settlement location , a mosque as Masjed Alreza was built which Ali ebne mahziar had willed that his body buried in mentioned mosque , there is a salon , at west part adjoining to the grave, probably it is the mosque that mentioned before .
