It is believed that the Nastaʿlīq style reached its highest elegance in Mir Emad's works.

He returned to Semnan and worked as a scribe in Shah Abbas's library and later on his court in the capital of Isfahan.

Mir Emad was later accused of being Sunni, a branch of Islam which was not tolerated under Safavids and implicitly sentenced to death by Shah Abbas.

In a night, on his way to Hamam, Mir Emad was assassinated by Masud Beik Mesgar Qazvini and for several days no one dared to bury his corpse.

Finally his pupil, Abu Torab Khattat Esfahani, buried him in Maghsoudbeyk mosque.
