Is it a condition for establishing the proof against a mushrik (one who associates partners with Allah) that it reaches him, or that he understands it?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the criterion for establishing the proof against one who commits major shirk (associating partners with Allah), which is directing worship to other than Allah? Is the criterion that the proof reaches him, or is it necessary that he understands it?

Answer:
If he understands the language in which the proof is conveyed to him, then establishing the proof is merely conveying it to him, and he understands it. If he is a non-Arab who does not understand, and you answer him in Arabic, which he does not understand, it is necessary to translate it for him so that he understands it. Yes.
