أَفَمَن شَرَحَ ٱللَّهُ صَدۡرَهُۥ لِلۡإِسۡلَٰمِ فَهُوَ عَلَىٰ نُورٖ مِّن رَّبِّهِۦۚ فَوَيۡلٞ لِّلۡقَٰسِيَةِ قُلُوبُهُم مِّن ذِكۡرِ ٱللَّهِۚ أُوْلَـٰٓئِكَ فِي ضَلَٰلٖ مُّبِينٍ
Afaman sharahal laahu sadrahoo lil Islaami fahuwa 'alaa noorim mir Rabbih; fa wailul lilqaasiyati quloobuhum min zikril laah; ulaaa'ika fee dalaalim mubeen
English Translation
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
