Surah Al-Baqarah, ayah 7

2:7

خَتَمَ ٱللَّهُ عَلَىٰ قُلُوبِهِمۡ وَعَلَىٰ سَمۡعِهِمۡۖ وَعَلَىٰٓ أَبۡصَٰرِهِمۡ غِشَٰوَةٞۖ وَلَهُمۡ عَذَابٌ عَظِيمٞ ٧

Khatamallāhu 'alā qulūbihim wa'alā sam'ihim wa'alā absārihim ghishāwatun walahum 'adhābun 'azīm

Allāh has set a seal upon their hearts and upon their hearing, and over their vision is a veil.12 And for them is a great punishment.
