Surah Ya-Sin, Verse 9

وَجَعَلۡنَا مِنۢ بَيۡنِ أَيۡدِيهِمۡ سَدّٗا وَمِنۡ خَلۡفِهِمۡ سَدّٗا فَأَغۡشَيۡنَٰهُمۡ فَهُمۡ لَا يُبۡصِرُونَ٩

wajaʿalnā min bayni aydīhim saddan wamin khalfihim saddan fa-aghshaynāhum fahum lā yub'ṣirūna

And We have put before them a barrier and behind them a barrier and covered them, so they do not see.
