'Ala' al-Dawla Simnani

Ala' al-Dawla Simnani was a Persian Sūfī of the Kubrāwī order, a writer and a teacher of Sufism. He was born in Semnan, Iran. He studied the tradition of Sufism from Nur al-Din Isfarayini. He also wrote many books on Sufism and Islam. Among his students were Mir Sayyid Ali Hamadani and Ashraf Jahangir Semnani
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. Some proponents of Arabized Islam were furious at Sufi elements that blended elements of Hinduism and deviated from the most strict interpretations of Shari'a. 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.
