Surah Al-Mulk — Ayah 7 (67:7)
إِذَآ أُلۡقُواْ فِيهَا سَمِعُواْ لَهَا شَهِيقٗا وَهِيَ تَفُورُ ٧
English translation (Saheeh International)
When they are thrown into it, they hear from it a [dreadful] inhaling while it boils up.
Brief commentary
When they will be thrown into the hellfire, they will hear an extremely evil sound: it will be bubbling like a boiling pot.
