The Quran

Preface

وَيُعَذِّبَ المُنافِقينَ وَالمُنافِقاتِ وَالمُشرِكينَ وَالمُشرِكاتِ الظّانّينَ بِاللَّهِ ظَنَّ السَّوءِ ۚ عَلَيهِم دائِرَةُ السَّوءِ ۖ وَغَضِبَ اللَّهُ عَلَيهِم وَلَعَنَهُم وَأَعَدَّ لَهُم جَهَنَّمَ ۖ وَساءَت مَصيرًا

Yusuf Ali

And that He may punish the Hypocrites, men and women, and the Polytheists men and women, who imagine an evil opinion of God. On them is a round¹ of Evil: the Wrath of God is on them: He has cursed² them and got Hell ready for them: and evil is it for a destination.

They will be encircled (or hemmed in) by Evil.
That is, deprived them of His Grace, on account of their continued rejection of it.
