It is reported that ʿAdī b. Ḥātim – Allāh be pleased with him – said:

You will remain upon good as long as you do not start approving of what you used to repudiate and as long as you do not repudiate what you used to know (to be right), and as long as your scholar (the knowledgeable) can speak amongst you without fear.

Ibn Baṭṭah, Al-Ibānah Al-Kubrā ḥadīth 26.
