Kisai Marvazi
Abul Hasan Abu Ishaq Kisa'i Marvazi was a 10th Persian poet.
Born in 953 CE and originating from Merv, he paid flattery first and foremost to the courts of the Samanids, but also to the Abbasids and Ghaznavids, particularly Mahmud of Ghazni.
He is said to have later converted to Shia Islam.
