Surah Al-Anbya — Ayah 100 (21:100)
لَهُمۡ فِيهَا زَفِيرٞ وَهُمۡ فِيهَا لَا يَسۡمَعُونَ ١٠٠
English translation (Saheeh International)
For them therein is heavy sighing, and they therein will not hear.
Brief commentary
Due to the severity of torture they shall face, they shall wail and breathe sharply. They will not be able to hear sounds due to the immense horrific torment that will afflict them.
