﴿ وَأَنَّا كُنَّا نَقْعُدُ مِنْهَا مَقَٰعِدَ لِلسَّمْعِ ۖ فَمَن يَسْتَمِعِ ٱلْءَانَ يَجِدْ لَهُۥ شِهَابًۭا رَّصَدًۭا ﴾

“notwithstanding that we were established in positions [which we had thought well-suited] to listening to [whatever secrets might be in] it: and anyone who now [or ever] tries to listen will [likewise] find a flame lying in wait for him!”

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.
