أَفَمَن شَرَحَ ٱللَّهُ صَدْرَهُۥ لِلْإِسْلَٰمِ فَهُوَ عَلَىٰ نُورٍۢ مِّن رَّبِّهِۦ ۚ فَوَيْلٌۭ لِّلْقَٰسِيَةِ قُلُوبُهُم مِّن ذِكْرِ ٱللَّهِ ۚ أُو۟لَٰٓئِكَ فِى ضَلَٰلٍۢ مُّبِينٍ
So is one whose breast Allah has expanded to [accept] Islam and he is upon a light from his Lord [like one whose heart rejects it]? Then woe to those whose hearts are hardened against the remembrance of Allah. Those are in manifest error.
