Nur al-Din Abdul Samad ibn Ali al-Isfahani (Persian: نورالدین عبدالصمد نطنزی), or Abdussamad Esfahani was an ascetic sage of the 13th century. Al-Isfahani hailed from Isfahan and stayed in Natanz.^[1] He was a student of Najib al-Din Bozgush Shirazni, himself a student of Shihab al-Din Umar Suhrawardi. His importance in Sufism stems from the fact that he was the teacher of Abdul Razzaq al-Kashani,^[2] the author of Ta'wilat al-Qur'an, a famous mystical exegesis (interpretation) of the Qur'an.^[3] Al-Isfahani died in 1299^[2] and he was succeeded by Shams al-Din Natanzi in his tariqah.

After his death, Abdul Samad al-Isfahani was buried in Natanz.^[1] A shrine was built over his grave under the orders of his disciple Shams al-Din Natanzi,^[1] with assistance from the vizier of the Mongol Ilkhanid ruler Muhammad Khudabandah, Zayn al-Din Mastari.^[1] The tomb of Al-Isfahani now stands in the center of the Jameh Mosque of Natanz, under its conical dome.^[1]
