Problem statement: The Iranians set about creating unique scripts in the early 14th century, resulting in introduction of three scripts: Tali’q, Nasta’liq, and Shikasta Nasta’liq. It remains apparent that the development of pens did not occur overnight, but rather over time.
Research objective: The primary goal of this study would be to investigate the trend of growth in individual letters (Mofradat) in Nasta’liq. Another objective of this study is to argue about how Naskh and Taliq have encouraged the emergence of Nasta’liq. 
Research method: As a contrast, we used letters in Baysonqori Shahname as an index of Nasta’liq following Mir Ali Tabrizi. We began comparing anthology scripts after identifying and classifying early Nasta’liq in Taj al-Din Ahmad Wazir’s anthology. According to what has already been stated, and also based on the belief that Mir Ali Tabrizi improved Nasta’liq and it appeared in Shiraz before that time, along with Taj al-Din Ahmad Wazir’s anthology in the University of Isfahan’s Central library, which is a valuable manuscript dating from 1380 . in Shiraz for Taj al-Din Ahmad Wazir during the Shah-Shojae kingship in Fars (1359-1385), this article deals with the formation of Nasta’liq separate letters (Mofradat) in 14th century in Iran.
Conclusion: The evidence suggests that Mir Ali Tabrizi is not the sole founder of Nasta’liq, but that he has just ordered the script according to some criteria. According to some documents, the early Nasta’liq script was also encountered in Shiraz at the same period as Mir Ali Tabrizi. On the other hand, the Nasta’liq script can be described as a hybrid of two script rules: Naskh and Taliq.
