The Quran

أَلَم تَرَ إِلَى الَّذينَ يَزعُمونَ أَنَّهُم آمَنوا بِما أُنزِلَ إِلَيكَ وَما أُنزِلَ مِن قَبلِكَ يُريدونَ أَن يَتَحاكَموا إِلَى الطّاغوتِ وَقَد أُمِروا أَن يَكفُروا بِهِ وَيُريدُ الشَّيطانُ أَن يُضِلَّهُم ضَلالًا بَعيدًا

Muhammad Asad

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 evil¹ - although they were bidden to deny it, seeing that Satan but wants to lead them far astray?

Lit., "who summon one another to the judgment [or "rule"] of the powers of evil (at-taghut): an allusion to people like those mentioned in verse 51 above, who, by their deference to what the Qur'an describes as at-taghut (see surah 2, verse 256), nullify all the good that they could derive from guidance through revelation.
