Nizam al-Din Hasan al-Nisaburi, whose full name was Nizam al-Din Hasan ibn Mohammad ibn Hossein Qumi Nishapuri (d. 1328/29) (Persian: نظام الدین حسن نیشاپوری) was a Persian Sunni[1][2][3] Islamic Shafi'i, Ash'ari scholar, mathematician, astronomer, jurist, Qur'an exegete, and poet.

He included data about the obliquity of the ecliptic and discussed the possibility that the transits of Venus and Mercury across the Sun had been seen.

A commentary on a zīj by Ṭūsī', it focused upon topics discussed in the Sharḥ, such as the positions of the planets in the night sky.

[4] Tawḍīḥ al‐Tadhkira ((توضیح الذکر), "Elucidation of the Tadhkira") was a commentary on Ṭūsī's al‐Tadhkira fī ʿilm al‐hayʾa ("Memento on Astronomy") that investigated topics that included alternatives to Ptolemy's model of the cosmos, and ideas to explain that accounted the known variations in the obliquity of the ecliptic.

Nīsābūrī's most famous work is his Ghara'ib al-Qur'an wa Ragha'ib al-Furqan (تفسير النيسابوري‎, "A Commentary on the Wonders of Quran in Exegesis"), also known as Tafsir al-Nisaburi).
