21:102
لَا يَسْمَعُونَ حَسِيسَهَا ۖ وَهُمْ فِى مَا ٱشْتَهَتْ أَنفُسُهُمْ خَـٰلِدُونَ
lā yasmaʿūna ḥasīsahā wahum fī mā ish'tahat anfusuhum khālidūna
they will not hear a murmur from it- and endlessly they will enjoy everything their souls desire.
They shall not hear the slightest sound of it (Hell), while they abide in that which their ownselves desire.
