Sura al-Zumar 39:22

أَفَمَن شَرَحَ ٱللَّـهُ صَدْرَهُۥ لِلْإِسْلَٰمِ فَهُوَ عَلَىٰ نُورٍ مِّن رَّبِّهِۦ فَوَيْلٌ لِّلْقَٰسِيَةِ قُلُوبُهُم مِّن ذِكْرِ ٱللَّـهِ أُو۟لَٰٓئِكَ فِى ضَلَٰلٍ مُّبِينٍ

a-fa-man sharaḥa allāhu ṣadrahu lil-islāmi fa-huwa ʿalā nūrin min rabbihi fa-waylun lil-qāsiyati qulūbuhum min dhikri allāhi ulāʾika fī ḍalālin mubīnin

Is one whose heart Allah has opened to Islam, so that he has received Enlightenment from Allah, (no better than one hard-hearted)? Woe to those whose hearts are hardened against celebrating the praises of Allah! they are manifestly wandering (in error)!
