Ala ud-Daula Simnani

Ala ud-Daula Simnani (Persian: علاءالدوله سمنانی, full name Shaikh Abu-Al-Makarim Rukn-ud-Din Ala ud-Daula Ahmed Bin Muhammad Bin Ahmed Bayabanki Simnani; 1261-1336) 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 Abud al- Rahman Asfariyeni. He also wrote many books on Sufism and Islam. Among his students were Ashraf Jahangir Semnani 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. 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.
