muhammad ibn zayd

muḥammad ibn zayd ibn muḥammad ibn ismā ` il ibn al-Ḥasan ibn zayd -lrb- died 3 october 900 -rrb- , also known as al-da ` ī al-ṣaghīr -lrb- `` the younger missionary '' -rrb- , was an alid who succeeded his brother , hasan -lrb- `` the elder missionary '' -rrb- , as ruler of the zaydid dynasty of tabaristan in 884 .
little is known of his early life , before coming to tabaristan after hasan established zaydid rule there in 864 .
he served his brother as a general and governor , and continued his policies after his accession .
his reign was troubled by rebellions and wars , most notably by the invasion of rafi ' ibn harthama in 889 -- 892 , which occupied most of his domains .
after rafi ' fell out of favour with the abbasids , muhammad recovered his position and secured the allegiance of rafi ' , but did not particularly support him against the saffarids .
in 900 , following the saffarids ' defeat by the samanids , he tried to invade khurasan , but was defeated and died of his wounds , whereupon tabaristan fell to the samanids .
