The ruling on delivering a talk on dhikr and instructing the attendees to engage in tasbih

Question:
(peace and blessings be upon him). A questioner says: A young man stood up and delivered a talk about the remembrance of Allah and about bringing the heart to presence during dhikr. Then he stopped and ordered those around him to glorify Allah thirty times while bringing the heart to presence. After that, he asked them about their state after the dhikr and its effect on them. Note that the dhikr is not collective; rather, each person remembers Allah to himself. What is your honorable opinion?

Answer:
This action is not permissible because it is a type of bid'ah (religious innovation). He prepares the ground and orders them to remember Allah, then asks what they found in their hearts. This is a type of Sufism. He should leave this practice. He should remember Allah, preach, remind, and continue reminding until he finishes and leaves the matter to them themselves, without setting a limit or time for them or binding them to specific words. Yes, if Allah benefits them with this sermon, they will believe in it within themselves. Yes.
