أَفَمَن شَرَحَ اللَّهُ صَدرَهُ لِلإِسلامِ فَهُوَ عَلىٰ نورٍ مِن رَبِّهِ ۚ فَوَيلٌ لِلقاسِيَةِ قُلوبُهُم مِن ذِكرِ اللَّهِ ۚ أُولـٰئِكَ في ضَلالٍ مُبينٍ

Consider the one whose heart God has opened to Submission, thus receiving enlightenment from his Lord. Woe to those whose hearts have hardened against God’s remembrance—those are in obvious error.
