Surah Az-Zumar Verse 22 - English Translation by A. J. Arberry
Surah Az-Zumarأَفَمَن شَرَحَ ٱللَّهُ صَدۡرَهُۥ لِلۡإِسۡلَٰمِ فَهُوَ عَلَىٰ نُورٖ مِّن رَّبِّهِۦۚ فَوَيۡلٞ لِّلۡقَٰسِيَةِ قُلُوبُهُم مِّن ذِكۡرِ ٱللَّهِۚ أُوْلَـٰٓئِكَ فِي ضَلَٰلٖ مُّبِينٍ
Is he whose breast God has expanded unto Islam, so he walks in a light from his Lord...? But woe to those whose hearts are hardened against the remembrance of God! Those are in manifest error
