﴿ وَأَنَّا لَمَّا سَمِعْنَا ٱلْهُدَىٰٓ ءَامَنَّا بِهِۦ ۖ فَمَن يُؤْمِنۢ بِرَبِّهِۦ فَلَا يَخَافُ بَخْسًۭا وَلَا رَهَقًۭا ﴾

“Hence, as soon as we heard this [call to His] guidance, we came to believe in it: and he who believes in his Sustainer need never have fear of loss or injustice.”

The jinn who heard the Quran not only accepted it immediately, but also became its propagators. This shows that whenever a true discourse reaches the ears of living people, it creates a two-fold effect—first, an open-hearted admission of its truth and second, a willingness to propagate its teachings.
