Daqiqi wrote an epic history of Iran which is begun by history of Zarathushtra and Gashtasb. Questions have been raised as to whether Daqiqi harbored some Zoroastrian beliefs, or was simply promoting Sassanian cultural trends in the wake of Samanid domination. Nevertheless, he is viewed to have been a Zoroastrian convert to Islam. A large number of couplets by him were included in the epic Shahname (Book of Kings) by the Persian epic poet Ferdowsi. Daqiqi was murdered by his favorite slave.
Some scholars[who?] speculate that Daqiqi wrote more, but the content was too controversial to be included in Shahname and later lost. Other poems by him have survived, published, among others, in Le premier poet Persan by G.Lazard.

Contemporary Persian and Classical Persian are the same language, but writers since 1900 are classified as contemporary. At one time, Persian was a common cultural language of much of the non-Arabic Islamic world. Today it is the official language of Iran, Tajikistan and one of the two official languages of Afghanistan.
