Tafsir of Ash-Shu`ara' 26:212

Verily, they have been removed far from hearing it. This is like what Allah tells us about the Jinn:

وأنا لمسنا السماء فوجدناها مليت حرسا شديدا وشهبا

وأنا كنا نقعد منها مقاعد للسمع فمن يستمع اﻻأن يجد له شهابا رصدا

وأنا ﻻأ ندري أشر أريد بمن في اﻻأرض أم أراد بهم ربهم رشدا

And we have sought to reach the heaven; but we found it filled with stern guards and flaming fires. And verily, we used to sit there in stations, to (steal) a hearing, but any who listens now will find a flaming fire watching him in ambush. And we know not whether evil is intended for those on the earth, or whether their Lord intends for them guidance.' (72:8-10)
