Ghaus-ul A’zam (radi Allahu anhu) says: “If a person is unable to differentiate between a true and false Murshid, he should read 2 Rakaats Nafil for achieving recognition of Allah at Tahajjud time. Then he should ask Allah to inform him of those pious people who will be able to guide him on the Right Path. He should beseech Allah to show him the person who will intoxicate him with Allah’s love and adorn the eyes of his heart with the light of Allah’s closeness and inform him of unseen happenings that he personally witnessed”. (Insha-Allah by doing so, one will receive the answer)(Al-Fath-ur Rabbani, pg.146)
If someone is unable to do this then he should seek the advise of a well versed Sunni Aalim. At times, people take advice from the ignorant and become Mureeds of Shaitaan. May Allah Ta’ala protect us all. Aameen.
