Az-Zumar (The Troops)

Surah 39 · Verse 22

Then is he, whose bosom Allah has opened for Islam so that he is (guided) by the light from his Fosterer, (like him who is in darkness)? So sorrowful is the state of those whose hearts are hardened against the remembrance of Allah, they are in a clear error.

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