ٱسْتَحْوَذَ عَلَيْهِمُ ٱلشَّيْطَـٰنُ فَأَنسَىٰهُمْ ذِكْرَ ٱللَّهِ ۚ أُو۟لَـٰٓئِكَ حِزْبُ ٱلشَّيْطَـٰنِ ۚ أَلَآ إِنَّ حِزْبَ ٱلشَّيْطَـٰنِ هُمُ ٱلْخَـٰسِرُونَ
Satan has overcome them and made them forget the remembrance of Allah. Those are the party of Satan. Unquestionably, the party of Satan - they will be the losers.
