Sura al-Nisāʾ 4:137

إِنَّ ٱلَّذِينَ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ ثُمَّ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ ثُمَّ ٱزْدَادُوا۟ كُفْرًا لَّمْ يَكُنِ ٱللَّـهُ لِيَغْفِرَ لَهُمْ وَلَا لِيَهْدِيَهُمْ سَبِيلًۢا

inna lladhīna āmanū thumma kafarū thumma āmanū thumma kafarū thumma azdādū kufran lam yakuni allāhu li-yaghfira lahum wa-lā li-yahdiyahum sabīlan

Those who believe, then reject faith, then believe (again) and (again) reject faith, and go on increasing in unbelief,- Allah will not forgive them nor guide them nor guide them on the way.

Sura al-Nisāʾ 4:173

فَأَمَّا ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ فَيُوَفِّيهِمْ أُجُورَهُمْ وَيَزِيدُهُم مِّن فَضْلِهِۦ وَأَمَّا ٱلَّذِينَ ٱسْتَنكَفُوا۟ وَٱسْتَكْبَرُوا۟ فَيُعَذِّبُهُمْ عَذَابًا أَلِيمًا وَلَا يَجِدُونَ لَهُم مِّن دُونِ ٱللَّـهِ وَلِيًّا وَلَا نَصِيرًا

fa-ammā lladhīna āmanū wa-ʿamilū l-ṣāliḥāti fa-yuwaffīhim ujūrahum wa-yazīduhum min faḍlihi wa-ammā lladhīna istankafū wa-istakbarū fa-yuʿadhdhibuhum ʿadhāban alīman wa-lā yajidūna lahum min dūni allāhi waliyyan wa-lā naṣīran

But to those who believe and do deeds of righteousness, He will give their (due) rewards,- and more, out of His bounty: But those who are disdainful and arrogant, He will punish with a grievous penalty; Nor will they find, besides Allah, any to protect or help them.
