﴿ ٱللَّهُ يَسْتَهْزِئُ بِهِمْ وَيَمُدُّهُمْ فِى طُغْيَٰنِهِمْ يَعْمَهُونَ ﴾

“God will requite them for their mockery, and will leave them for a while in their overweening arrogance, blindly stumbling to and fro:”

God Himself mocks them requiting them for their mockery leaving them that is giving them respite in their insolence that is in their transgressing the limits of unbelief; bewildered wavering in perplexity ya‘mahūn is a circumstantial qualifier.
