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 matters step by step and do what you can; Allah does not ask you for what you cannot do. Take matters step by step, little by little. Do not denounce all matters in one lump; rather, take matters step by step, little by little. And the presentation ; do not let this verse be hidden from you. And the debate , but the foundation is that you learn first. As for the one who commands and forbids and calls to Allah without knowledge or insight, but relies on zeal, that is no problem. And this is the affliction of the Muslims today: ignorance, ignorance, ignorance. Yes.
