The rising took place when the protecting Persian garrison withdrew from Yemen.
The Sasanians, this time with a force of 4,000 men, managed to reconquer Yemen and install Sayf’s son, Maʿdī Kareb as ruler.
[2] A pre-Islamic Arabian poet, Umayya bin Abi al-Salt, has praised the victory of the Persians in one of his poems.
His poem is recorded in Abu al-Faraj al-Isfahani's Kitab al-Aghani.
The names of the successive Persian governors are as follows, according to Tabari (there is some variation in the sources over the names):[2] The Persian garrison of soldiers and officials settled down in Sana'a and its vicinity and intermarried with the local Arab population, and the sons of these Persian fathers and Arab mothers, with their descendants, became known as the abnāʾ.
