The World Forum for Proximity of Islamic Schools of Thought (WFPIST) as well as Tehran's Ecumenical Society (Persian: مجمع جهانی تقریب مذاهب اسلامی) is a forum that was established in October 1990 by order of Ayatollah Seyed Ali Khamenei in Tehran for the reconciliation between different Islamic schools and branches.

For instance, Iranian scholar Sheikh Mohamad Taqi Qomi emigrated to Egypt in the mid-twentieth century.

There he established a forum in Cairo that was named jam'iyyat al-tagrib bayn al-madhahib al-islamiyya (Arabic: دارالتقریب بین المذاهب الاسلامیة بالقاهره)in 1948.

A number of scholars of Al-Azhar and some Egyptian politicians supported this forum and its secretary general Sheikh Qomi.

Another attempt to achieve proximity between different schools of Islam was the publication of Risalat al-Islam Magazine (Arabic: مجلة رسالة الاسلام) by jam'iyyat al-tagrib bayn al-madhahib al-islamiyya in Cairo.
