Is it permissible to help build a Qur'anic school that is expected to be a breeding ground for religious innovations (bid'ah)?

Question:
May Allah reward you. This questioner says: I am the imam of a mosque, and my father has a Sufi tendency, and he is in the process of. He says: I am the imam of a mosque, and my father has a Sufi tendency, and he is in the process of building a Qur'anic school for memorizing the Qur'an. He is now asking me to help him raise money to complete this construction, knowing that I am aware that this school will be a breeding ground for Sufism and a place for spreading religious innovation (bid'ah) and superstition. The question is: Is it permissible for me to help him, given his promise to me that it will open the door for the people of the Sunnah to memorize the Qur'an there?

Answer:
If it is exclusively for memorizing the Qur'an, there is nothing wrong with it. But if it is like what you say, a stronghold of Sufism, then no, do not help him with this.
