Murshids are two types:
A. Murshid Aam (General Guide,) and
B. Murshid Khaas (Specific Guide)
The Murshids Khaas comprises of the Sheikhul Ittisaal and the Sheikhul Isaal.
The Murshid Aam comprises of the Quran, Hadith, the writings of the Jurists, the Murshids, authorities of Tasawwuf, the writings of the scholars, and the writings of the people of guidance and righteousness. The guide of the general public is the Kalaam (Speech and Writings) of the Scholars. The guide of the Ulema or Scholars is the writings of the Imaams of Fiqh. The guide of Imams of Fiqh is the Sunnah and Hadith of Nabi (sallal laahu alaihi wasallam). The guide of the Holy Prophet (sallal laahu alaihi wasallam) is the Quran/Speech/Revelation of Allah.
From this it can be seen that the Murshid Aam is an absolute necessity. A person without guidance of both the Murshids, i.e. Khaas and Aam is under the reign of Shaitaan. It is in this sense that A’la Hazrat, Moulana Ahmed Raza Khan Barelwi (radi Allahu anhu) writes that Sayyiduna Baayazid Bustaami’s (radi Allahu anhu) declaration in “Awaariful Ma’arif” that those without a Murshid (Khaas and Aam) have Shaitaan as their guide.
