The Tanzeem-e-Islami is an Islamic organisation based in Lahore, Pakistan that advocates the implementation of the Quran and Sunnah in the social, cultural, legal, political, and the economic spheres of life; and the "refutation of the misleading thoughts and philosophy of modernity".
The organization has emerged as a "strong conservative force" within Pakistan. It opposes the development of a "modern secular curriculum" in universities, "friendly relations with the United States", and the influx of "Western values and vices" into Pakistan. While it supports jihad, it emphasizes the need for "passive resistance and perseverance", to first gain a "substantial foothold" and build momentum in society. While primarily active in Pakistan, TI has developed "affiliates based in the Indo-Pakistani Muslim communities in North America and Europe".
The organization was formed by author and Islamic scholar Israr Ahmed in 1975 following his break with the Jamaat-e-Islami (JI) party in 1957, after the JI entered electoral politics in Pakistan. Ahmed's son, Hafiz Akif Saeed assumed the leadership role of the organization after the voluntary resignation of the founder in 2002.
