'Ala' al-Dawla Simnani (Persian: علاءالدوله سمنانی; November 1261 – 6 March 1336) was a Persian Sūfī of the Kubrāwī order,[1] a writer and a teacher of Sufism.
He studied the tradition of Sufism from Nur al-Din Isfarayini.
Among his students were Ashraf Jahangir Semnani[3] and Mir Sayyid Ali Hamadani.
There was disagreement in those days among ulema and Sufis about various cultural issues, most notably the distinction of Persianate Ajami Islam that was more widespread than the more puritanical Arabized forms.
Simnani was a central figure in these debates as the intellectual wellspring of Central Asian mysticism, contrasted with the views of Ibn Arabi, who decried the Sufi philosophies.
