Da'wah in lands of disbelief while remaining silent about the errors of the people of innovation

Question:
Honorable Shaykh, may Allah grant you success. This is a questioner from outside this country who says: We are in a land of disbelief, and the administration of the mosques in those lands is in the hands of the people of innovation, the Maturidiyyah and the Asha'irah. He says: If I want to call to Allah, I am required to remain silent about their errors. So, am I required to proceed to perform my work of da'wah in that land while remaining silent about the errors of these people?

Answer:
My brother, take things step by step and do what you can, for Allah does not ask you to do what you are unable to do. Take things step by step, little by little. Do not reject all matters in one lump; rather, take things step by step, little by little. And the presentation of wisdom and good exhortation should not be absent from you. This verse is not to be overlooked: and the best way of arguing is . But the foundation is that you learn first. As for the one who commands and forbids and calls people to Allah without knowledge or insight, but relies on zeal, that is a problem. And this is the affliction of the Muslims today: ignorance, ignorance, ignorance. Yes.
