أَفَمَن شَرَحَ ٱللَّهُ صَدْرَهُۥ لِلْإِسْلَـٰمِ فَهُوَ عَلَىٰ نُورٍ مِّن رَّبِّهِۦ ۚ فَوَيْلٌ لِّلْقَـٰسِيَةِ قُلُوبُهُم مِّن ذِكْرِ ٱللَّهِ ۚ أُو۟لَـٰٓئِكَ فِى ضَلَـٰلٍ مُّبِينٍ

What about the one whose heart God has opened in devotion to Him, so that he walks in light from his Lord? Alas for those whose hearts harden at the mention of God! They have clearly lost their way.
Is he whose breast Allâh has opened to Islâm, so that he is in light from His Lord (as he who is a non-Muslim)? So woe to those whose hearts are hardened against remembrance of Allâh! They are in plain error!
