وَلَقَدْ جِئْتُمُونَا فُرَٰدَىٰ كَمَا خَلَقْنَٰكُمْ أَوَّلَ مَرَّةٍۢ وَتَرَكْتُم مَّا خَوَّلْنَٰكُمْ وَرَآءَ ظُهُورِكُمْ ۖ وَمَا نَرَىٰ مَعَكُمْ شُفَعَآءَكُمُ ٱلَّذِينَ زَعَمْتُمْ أَنَّهُمْ فِيكُمْ شُرَكَٰٓؤُا۟ ۚ لَقَد تَّقَطَّعَ بَيْنَكُمْ وَضَلَّ عَنكُم مَّا كُنتُمْ تَزْعُمُونَ
Now have ye come unto Us solitary as We did create you at the first, and ye have left behind you all that We bestowed upon you, and We behold not with you those your intercessors, of whom ye claimed that they possessed a share in you. Now is the bond between you severed, and that which ye presumed hath failed you.
Surah Al-An'aam(6:94)
