أَفَمَن شَرَحَ ٱللَّهُ صَدۡرَهُۥ لِلۡإِسۡلَٰمِ فَهُوَ عَلَىٰ نُورٖ مِّن رَّبِّهِۦۚ فَوَيۡلٞ لِّلۡقَٰسِيَةِ قُلُوبُهُم مِّن ذِكۡرِ ٱللَّهِۚ أُوْلَـٰٓئِكَ فِي ضَلَٰلٖ مُّبِينٍ
So I ask about a person whose heart Allah has opened up for Islam, and consequently he proceeds in a light from his Lord. (Can he be equal to the one whose heart is hardened?) So, woe to those whose hearts are too hard to remember Allah. Those are wandering in open error.
ٱللَّهُ نَزَّلَ أَحۡسَنَ ٱلۡحَدِيثِ كِتَٰبٗا مُّتَشَٰبِهٗا مَّثَانِيَ تَقۡشَعِرُّ مِنۡهُ جُلُودُ ٱلَّذِينَ يَخۡشَوۡنَ رَبَّهُمۡ ثُمَّ تَلِينُ جُلُودُهُمۡ وَقُلُوبُهُمۡ إِلَىٰ ذِكۡرِ ٱللَّهِۚ ذَٰلِكَ هُدَى ٱللَّهِ يَهۡدِي بِهِۦ مَن يَشَآءُۚ وَمَن يُضۡلِلِ ٱللَّهُ فَمَا لَهُۥ مِنۡ هَادٍ
Allah has sent down the best discourse, a book containing subjects resembling each other, mentioned again and again, shivered from which are the skins of those who have awe of their Lord. Then, their skins and their hearts become soft enough to tend to the remembrance of Allah. This is the Guidance of Allah with which He brings to the right path whomsoever He wills. As for the one whom Allah lets go astray, for him there is no one to guide.
أَفَمَن يَتَّقِي بِوَجۡهِهِۦ سُوٓءَ ٱلۡعَذَابِ يَوۡمَ ٱلۡقِيَٰمَةِۚ وَقِيلَ لِلظَّـٰلِمِينَ ذُوقُواْ مَا كُنتُمۡ تَكۡسِبُونَ
Tell Me about the one who tries to save himself from the worst punishment with his face on the Day of Judgment, (whether he is equal to the one who is not liable to any punishment.) And it will be said to the wrongdoers, “Have a taste of what you used to earn.”
