﴿ فَخَسَفْنَا بِهِۦ وَبِدَارِهِ ٱلْأَرْضَ فَمَا كَانَ لَهُۥ مِن فِئَةٍۢ يَنصُرُونَهُۥ مِن دُونِ ٱللَّهِ وَمَا كَانَ مِنَ ٱلْمُنتَصِرِينَ ﴾

“And thereupon We caused the earth to swallow him and his dwelling; and he had none and nothing to succour him against God, nor was he of those who could succour themselves.”

So We caused the earth to swallow him Korah and his dwelling and he had no host to help him besides God that is other than Him to protect him from destruction nor was he of those who can rescue themselves from it.
