Nur al-Din Abdul Samad ibn Ali al-Isfahani (Persian: نورالدین عبدالصمد نطنزی), or Abdussamad Esfahani was an ascetic sage of the 13th century.

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.

[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.
