خَالِدِينَ فِيهَا أَبَدًاWherein they will abide forever,means, they will stay there forever and ever, never leaving or finding relief from it.لاَّا يَجِدُونَ وَلِيًّا وَلَا نَصِيرًاand they will find neither a a protector nor a helper.means, they will have no saviour to help them or rescue them from their predicament.Then Allah says:يَوْمَ تُقَلَّبُ وُجُوهُهُمْ فِي النَّارِ يَقُولُونَ يَا لَيْتَنَا أَطَعْنَا اللَّهَ وَأَطَعْنَا الرَّسُولَا
