What is the ruling on a student of knowledge going out with the Tabligh group?

Question:
Honorable Shaykh, there is a group called the Dawah group that has a strange influence on sinners. They go to a center in one of the countries. Is it advisable for someone with religious knowledge to go with them, given that they consider it an error for anyone who does not go out with them for this work for forty days or four months?

Answer:
This is the Tabligh group. The Tabligh group is a known group; they have Sufism and they have religious innovations (bid'ah). Is it not permissible to go with them? The one who knows the truth does not need them, and the one who has sins repents to Allah without them. He repents to Allah anywhere, in his home or in his country. He does not need to repent only with the Tabligh group. The door of repentance is open, and whoever repents, Allah accepts his repentance. So there is no need for him to go with the Tabligh group and the ignorance and religious innovations (bid'ah) they have. Yes.
