﴿ 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 ﴾

“ART THOU NOT aware of those who claim that they believe in what has been bestowed from on high upon thee, [O Prophet,] as well as in what was bestowed from on high before thee, [and yet] are willing to defer to the rule of the powers of evil - although they were bidden to deny it, seeing that Satan but wants to lead them far astray?”

(Hast thou not seen) have you not been informed, O Muhammad, about (those who pretend that they believe in that which is revealed unto thee) i.e. the Qur'an (and that which was revealed before thee) i.e. the Torah, (how they would go for judgement (in their disputes) to false deities) Ka'b Ibn al-Ashraf (when they have been ordered) in the Qur'an (to abjure them?) to disavow them. (Satan would mislead them far astray) from the Truth and guidance. This verse was revealed about a hypocrite by the name of Bishr whom 'Umar Ibn al-Khattab had killed. This hypocrite had a dispute with a Jewish man.
