(Zumar) 39 : 22
أَفَمَنْ شَرَحَ اللَّهُ صَدْرَهُ لِلْإِسْلَامِ فَهُوَ عَلَىٰ نُورٍ مِنْ رَبِّهِ ۚ فَوَيْلٌ لِلْقَاسِيَةِ قُلُوبُهُمْ مِنْ ذِكْرِ اللَّهِ ۚ أُولَٰئِكَ فِي ضَلَالٍ مُبِينٍ

Then is the one whose chest Allah has widened to Islam, thus he is upon a Light from His Lord; then whose hearts are hardened from the remembrance of Allah have the Wail, such is in the manifest astray.

Light from the Lord Allah is Adhikr, only with which remembrance of Allah can be kept in the heart always. The one who is living in the Light of Adhikr is satisfied with Islam. Those who live neglecting Adhikr after It is received are living in a strayed way and have the ‘wail’ valley in the Hereafter, which is one of the seven doors of Hell, as explained in verse 15: 44. The Arabic Quran-reading Fujjar, including the hypocrites and their blind followers, have forgotten Allah, and they are having evil thoughts about Allah so that His wrath and curse are affected upon them, and they have an evil consequence, and for them, Hell is kept prepared as told in verses 48:6; 9: 67-68 and 98: 6. See explanation 6: 25-26; 10: 88; 57: 16.
