AZ ZUMAR — Ayat 22

أَفَمَن شَرَحَ اللَّهُ صَدْرَهُ لِلْإِسْلَامِ فَهُوَ عَلَى نُورٍ مِّن رَّبِّهِ فَوَيْلٌ لِّلْقَاسِيَةِ قُلُوبُهُم مِّن ذِكْرِ اللَّهِ أُوْلَئِكَ فِي ضَلَالٍ مُبِينٍ

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.
