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

Afaman sharaha Allahu sadrahulil-islami fahuwa AAala noorin min rabbihi fawaylunlilqasiyati quloobuhum min thikri Allahi ola-ikafee dalalin mubeen

So is one whose breast Allāh has expanded to [accept] Islām and he is upon [i.e., guided by] a light from his Lord [like one whose heart rejects it]? Then woe to those whose hearts are hardened against the remembrance of Allāh. Those are in manifest error.
