Verse relating to Ka'b bin Al-Ashraf

أَلَمْ تَرَ إِلَى ٱلَّذِينَ أُوتُوا۟ نَصِيبًۭا مِّنَ ٱلْكِتَٰبِ يُؤْمِنُونَ بِٱلْجِبْتِ وَٱلطَّٰغُوتِ وَيَقُولُونَ لِلَّذِينَ كَفَرُوا۟ هَٰٓؤُلَآءِ أَهْدَىٰ مِنَ ٱلَّذِينَ ءَامَنُوا۟ سَبِيلًا

Hast thou not turned Thy vision to those who were given a portion of the Book? they believe in sorcery and Evil, and say to the Unbelievers that they are better guided in the (right) way Than the believers!

أُو۟لَٰٓئِكَ ٱلَّذِينَ لَعَنَهُمُ ٱللَّهُ ۖ وَمَن يَلْعَنِ ٱللَّهُ فَلَن تَجِدَ لَهُۥ نَصِيرًا

They are (men) whom Allah hath cursed: And those whom Allah Hath cursed, thou wilt find, have no one to help.

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 turned Thy vision to those who declare that they believe in the revelations that have come to thee and to those before thee? Their (real) wish is to resort together for judgment (in their disputes) to the Evil One, though they were ordered to reject him. But Satan's wish is to lead them astray far away (from the right).
