Praying Behind an Imam from the Tabligh Group

Question:
Is it permissible to pray behind an imam from the Tablighi Jama'ah, or is it not? If it is not permissible, should we, as the group performing Hajj, write to the Waqf to have him replaced, or what should we do?

Answer:
The creation is sound, except for the one who has no defect in his creed and no shirk (associating partners with Allah). The one who has no shirk or apostasy, it is valid to pray behind him. So the prayer is valid, if Allah wills. However, one should strive with the Waqf to replace him with someone in a better state and more adherent to the Sunnah, so that there is no confusion for the people. The imams who are upright upon the Sunnah are many, praise be to Allah. We do not need such a person.
As for the prayer itself, as long as he has no shirk and no kufr (disbelief), the prayer behind him is valid. Even if he has bid'ah (religious innovation), as long as his bid'ah does not take him out of the religion, his prayer is valid, and the prayer of those behind him is valid. However, this is with the effort to replace him with someone better than him. Yes.
