أَلَمْ تَرَ إِلَى ٱلَّذِينَ يَزْعُمُونَ أَنَّهُمْ ءَامَنُوا۟ بِمَآ أُنزِلَ إِلَيْكَ وَمَآ أُنزِلَ مِن قَبْلِكَ يُرِيدُونَ أَن يَتَحَاكَمُوٓا۟ إِلَى ٱلطَّٰغُوتِ وَقَدْ أُمِرُوٓا۟ أَن يَكْفُرُوا۟ بِهِۦ وَيُرِيدُ ٱلشَّيْطَٰنُ أَن يُضِلَّهُمْ ضَلَٰلًۢا بَعِيدًۭا
Hast thou not seen those who pretend that they believe in that which is revealed unto thee and that which was revealed before thee, how they would go for judgment (in their disputes) to false deities when they have been ordered to abjure them? Satan would mislead them far astray.
