quran:15:18 –

Except one who steals a hearing and is pursued by a clear burning flame.  

except the one who listens by stealth — he is pursued by a clear flame, a shining meteor that burns him, or pierces him or drives him insane.
القرآن:١٥:١٨ –

إِلَّا مَنِ اسْتَرَقَ السَّمْعَ فَأَتْبَعَهُ شِهَابٌ مُبِينٌ  

{إلا} لكن {من استرق السمع} خطفه {فأتبعه شهاب مبين} كوكب يضيء ويحرقه أو يثقبه أو يخبله.
