سورة الزمر

أَفَمَنْ شَرَحَ اللَّهُ صَدْرَهُ لِلْإِسْلَامِ فَهُوَ عَلَىٰ نُورٍ مِنْ رَبِّهِ ۚ فَوَيْلٌ لِلْقَاسِيَةِ قُلُوبُهُمْ مِنْ ذِكْرِ اللَّهِ ۚ أُولَٰئِكَ فِي ضَلَالٍ مُبِينٍ ﴿٢٢﴾

Surah az-Zumar

22. What about someone whose chest Allah has expanded for Submission, so he is enlightened by his Lord? So woe to those whose hearts are hardened against the remembrance of Allah. These are in obvious error.
