Abu Hafs Sughdi (Persian: ابوحفص سغدی) was an Iranian[1] poet and musician of the late-third/ninth to early-fourth/tenth century.
But, it is believed that Abu Hafs was the first poet to write poetry in the New Persian language.
According to some primary sources, he was the author of an Arabic-Persian dictionary, which is lost today, but was available as late as the 11th century AH.
It is also possible that the author of this dictionary was another person also named Abu Hafs.
[2] Shams-i Qays-i Razi is the first person who mentioned Abu Hafs in al-Muʿjam fī maʿāyīr ashʿār al-ʿajam.
