Tolu-e-Islam (Dawn of Islam)
Tolu-e-Islam does not belong to any political party nor does it belong to any religious group or sect (it has nothing to do with the sect known as Ahle-Quran). Also, it does not want to create any new sect because such acts of creating sects in Deen are Shirk. Tolu-e-Islam does not advocate any change in the way different sects in the Ummah are practicing the five pillars. In fact, it adheres to the same practices. Tolu-e-Islam seeks to propagate the Quranic teachings so that the system of "Khilafat ‘Ala Minhaj-e-Risalat" is once again established.

OIC The Organization of the Islamic Conference
Set up by the Kings and Heads of State and Government of Islamic States, in 1969, was the concrete expression of a great awareness, on the part of the Ummah, of the necessity to establish an Organization embodying its aspirations and capable of carrying out its just struggle against the various dangers which threatened it and still persist.
