Is it good to involve adherents of a false creed in a center for rehabilitating preachers, with the fear of bearing their burden should they become callers to their methodology, and what is the limit for benefiting from them?

Enrolling children in a center is more fitting to increase their learning and to know the correct methodology, especially if the books of the correct methodology are prescribed in the center and its teachers are competent. An example of this is the story of Sheikh Muhammad Aman al-Jami about a teacher in India who used to supplicate against Sheikh Muhammad ibn Abd al-Wahhab, but then changed his stance after reading the book "Kitab al-Tawhid" with its cover removed and admired it. He then discovered that it was authored by Sheikh Muhammad ibn Abd al-Wahhab, so he repented and changed his supplication.
