It is reported from ʿAbdullah b. Mas’ūd – Allah be pleased with him – that he said:
For every bid’ah with which Islām is plotted against, Allah has a beloved worshipper (walī) who refutes and repels it and speaks about its signs, so take the full opportunity of attending such places, and trust in Allah.
Ibn Waddāḥ, Al-Bid’ah p5.
