It is reported from ‘Abdullah b. Mas’ûd – Allah be pleased with him – that he said:

For every bid’ah with which Islâm is plotted against, Allah has a beloved worshipper (walî) who refutes and repels it and speaks about its signs, so take the full opportunity of attending such places, and trust in Allah.

Ibn Waddâh, Al-Bid’ah p5.
