﴿ وَلَوْ نَشَآءُ لَطَمَسْنَا عَلَىٰٓ أَعْيُنِهِمْ فَٱسْتَبَقُوا۟ ٱلصِّرَٰطَ فَأَنَّىٰ يُبْصِرُونَ ﴾
“NOW HAD IT BEEN Our will [that men should not be able to discern between right and wrong], We could surely have deprived them of their sight, so that they would stray forever from the [right] way: for how could they have had insight [into what is true]?”
