أَفَمَن شَرَحَ ٱللَّهُ صَدْرَهُۥ لِلْإِسْلَـٰمِ فَهُوَ عَلَىٰ نُورٍ مِّن رَّبِّهِۦ ۚ فَوَيْلٌ لِّلْقَـٰسِيَةِ قُلُوبُهُم مِّن ذِكْرِ ٱللَّهِ ۚ أُو۟لَـٰٓئِكَ فِى ضَلَـٰلٍ مُّبِينٍ
Afaman sharahal laahu sadrahoo lil Islaami fahuwa 'alaa noorim mir Rabbih; fa wailul lilqaasiyati quloobuhum min zikril laah; ulaaa'ika fee dalaalim mubeen
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 the one whose heart God has opened to surrender, so that he walks in a light from his Lord, [like one whose heart is closed]? Woe to those whose hearts have hardened against the remembrance of God — they are in clear error.
