فِي قُلُوبِهِمْ مَرَضٌ فَزَادَهُمُ اللَّهُ مَرَضًا ۖ وَلَهُمْ عَذَابٌ أَلِيمٌ بِمَا كَانُوا يَكْذِبُونَ
10. In their hearts is disease, so Allah has increased their disease; and for them is a painful punishment because they [habitually] used to lie.
إِنَّمَا يَسْتَأْذِنُكَ الَّذِينَ لَا يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَارْتَابَتْ قُلُوبُهُمْ فَهُمْ فِي رَيْبِهِمْ يَتَرَدَّدُونَ
45. Only those would ask permission of you who do not believe in Allah and the Last Day and whose hearts have doubted, and they, in their doubt, are hesitating.
لَا يَزَالُ بُنْيَانُهُمُ الَّذِي بَنَوْا رِيبَةً فِي قُلُوبِهِمْ إِلَّا أَنْ تَقَطَّعَ قُلُوبُهُمْ ۗ وَاللَّهُ عَلِيمٌ حَكِيمٌ
110. Their building which they built will not cease to be a [cause of] skepticism in their hearts until their hearts are stopped. And Allah is Knowing and Wise.
وَمِنَ النَّاسِ مَنْ يَعْبُدُ اللَّهَ عَلَىٰ حَرْفٍ ۖ فَإِنْ أَصَابَهُ خَيْرٌ اطْمَأَنَّ بِهِ ۖ وَإِنْ أَصَابَتْهُ فِتْنَةٌ انْقَلَبَ عَلَىٰ وَجْهِهِ خَسِرَ الدُّنْيَا وَالْآخِرَةَ ۚ ذَٰلِكَ هُوَ الْخُسْرَانُ الْمُبِينُ
11. And of the people is he who worships Allah on an edge. If he is touched by good, he is reassured by it; but if he is struck by trial, he turns on his face [to the other direction]. He has lost [this] world and the Hereafter. That is what is the manifest loss.
