Farīd'd-dīn Maʼsud, son of Ḥāfis Ibrāhim Munajim was the court astronomer of Shāhjahān. He was considered as a great scholar in mathematics, astronomy, geometry. etc. He wrote perhaps two works viz. *Sirājul Istikhrai* and *Zij-i Shāhjahānī* in 1629 A. D. The former deals with eras, calculations of dates and principles of computation of almanacs. The latter is on calendars and astronomical tables. The manuscripts of both the works are available in the State Central Library, Hyderabad.
