Had Allāh known any good in them, He would have made them hear. And if He had made them hear, they would [still] have turned away, while they were refusing.

Tafsir
If Allah knew that there was good in these idolaters who reject the truth, He would have made them listen in a way that was beneficial to them, so that they would understand the proof and evidence; but He knows that there is no good in them, and that if He made them hear, they would still turn away stubbornly, rejecting what they heard.
