48:6
وَيُعَذِّبَ ٱلْمُنَـٰفِقِينَ وَٱلْمُنَـٰفِقَـٰتِ وَٱلْمُشْرِكِينَ وَٱلْمُشْرِكَـٰتِ ٱلظَّآنِّينَ بِٱللَّهِ ظَنَّ ٱلسَّوْءِ ۚ عَلَيْهِمْ دَآئِرَةُ ٱلسَّوْءِ ۖ وَغَضِبَ ٱللَّهُ عَلَيْهِمْ وَلَعَنَهُمْ وَأَعَدَّ لَهُمْ جَهَنَّمَ ۖ وَسَآءَتْ مَصِيرًا
And [that] He may punish the hypocrite men and hypocrite women, and the polytheist men and polytheist women - those who assume about Allah an assumption of evil nature. Upon them is a misfortune of evil nature; and Allah has become angry with them and has cursed them and prepared for them Hell, and evil it is as a destination.
