Today, spirituality is quite common. It is a source of earning. A strong syndicate is now doing spirituality business. From political leaders to people are going to a spiritual leader for fulfilling their eternal will. They believe everything will be done by their pir wish and pir makes their life more easy and wealthy. That’s why Pir is now a brand.
Therefore, Pir has many followers who get mozeza (charisma) from their pir. For instance, a stroke patient who should go immediately to the hospital for his curing but he goes to his pir house because he believes his illness will be cured by their pir will.
Religiously there is a restriction for praying to Pir because it means Allah is none. So it is the faith to Allah and everybody should remain this believe without any doubt. If anybody prays for anything to any pir, he loses his faith to Allah and it is unrecoverable destruction of his iman.
