What is the ruling on the Sufis performing their religious innovations (bid'ah)?

Question:
This person is asking about the custom of the Sufis in a certain country, where they gather in the mosque for three days a week, form a circle, and all recite the Rafi'i party (a specific set of dhikr).

Answer:
My brother, all of this is invalid (batil), none of it has a basis, and it is all religious innovation (bid'ah). Neither al-Rafi'i has a prescribed dhikr, nor does so-and-so have a prescribed dhikr. Dhikr is what is mentioned in the Book and the Sunnah from the Messenger of Allah (peace and blessings be upon him).
So we follow the Messenger (peace and blessings be upon him); we do not follow al-Rafi'i, nor so-and-so, nor so-and-so. We follow the Messenger (peace and blessings be upon him). And we remember Allah without forming circles or gathering. We remember Allah; everyone remembers Allah. "Remember Allah standing, sitting, and lying on your sides," as Allah the Exalted said . And He, the Majestic and Exalted, said . So you remember Allah in any place, alone, not with anyone else. You remember Allah while riding, you remember Allah while walking, you remember Allah while lying down, you remember Allah in your bowing and prostration, without groups and without "yes."
