Mentioning the truth held by the opponent when refuting him

Question:
Honorable Shaykh, he says: Does it mean that because we accept the truth from the opponent without the falsehood, that when we speak about them by way of warning and disapproval, we should mention the good they have when refuting them, or is the matter different?

Answer:
The intention is this: we mention the virtues they have; we do not mention speech that contains such and such, containing truth and falsehood. As for the truth, it is such and such, and as for the falsehood, it is such and such. As for the man, we neither praise him nor blame him. What he has is merely a test of the refutation of the article. But we do not say, "They said, they said, they said." There may be some truth in it. We say, "Speech that resembles such and such, which agrees on truth, and speech that agrees on falsehood."
As for the man who did not call upon his Lord, saying, "So-and-so is good, and so-and-so, and what are the virtues, and what actually happened."
