قُلْ هَلْ أُنَبِّئُكُم بِشَرٍّۢ مِّن ذَٰلِكَ مَثُوبَةً عِندَ ٱللَّهِ ۚ مَن لَّعَنَهُ ٱللَّهُ وَغَضِبَ عَلَيْهِ وَجَعَلَ مِنْهُمُ ٱلْقِرَدَةَ وَٱلْخَنَازِيرَ وَعَبَدَ ٱلطَّٰغُوتَ ۚ أُو۟لَٰٓئِكَ شَرٌّۭ مَّكَانًۭا وَأَضَلُّ عَن سَوَآءِ ٱلسَّبِيلِ
Shall I tell thee of a worse (case) than theirs for retribution with Allah? (Worse is the case of him) whom Allah hath cursed, him on whom His wrath hath fallen and of whose sort Allah hath turned some to apes and swine, and who serveth idols. Such are in worse plight and further astray from the plain road.
Surah Al-Maaida(5:60)
