Praise be to Allah.
The abhorrent nature of shirk, wrongdoing and shameful deeds is something that is well-established even if one has not heard of the teachings of the Prophets, but the (divine) punishment of one who does such deeds does not become due until after the teachings reach him
Praise be to Allah.
What Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) meant by these words was to highlight that shirk is wrong and blameworthy, and that the one who commits shirk is to be described as a mushrik; his action is abhorrent and blameworthy, regardless of whether or not proof with evidence has been established against the mushrik, because shirk is abhorrent in all cases, before the sending of the message and afterwards.
Then he explained: The (divine) punishment of this mushrik is conditional and cannot be carried out unless matters are explained and proof is established. Therefore he does not deserve to be punished except after the Messenger has come and after the matter has been explained and made clear. If he associates others with Allah after the matter has been explained, then he deserves punishment, but if he did that before becoming aware of the teachings that were brought by the Messenger, he does not deserve punishment until proof is established against him.
