وَجَعَلْنَا مِنۢ بَيْنِ أَيْدِيهِمْ سَدًّا وَمِنْ خَلْفِهِمْ سَدًّا فَأَغْشَيْنَـٰهُمْ فَهُمْ لَا يُبْصِرُونَ
And We have put before them a barrier and behind them a barrier and covered them, so they do not see.
أُو۟لَـٰٓئِكَ عَلَىٰ هُدًى مِّن رَّبِّهِمْ ۖ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ
Those are upon [right] guidance from their Lord, and it is those who are the successful.
