Surah 4. An-Nisaa', Ayah 60

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}, note [250]), nullify all the good that they could derive from guidance through revelation.

The immediate reference was to the Hypocrites (Munafiqin) of Madinah but the words are general, and the evil of hypocrisy has to be dealt with in all ages. The type of these men is what is called Mr. Facing-both-ways in Bunyan's "Pilgrim's Progress." Such men declare that they are always with the Right, but calmly intrigue with Evil and Injustice, and even make Injustice their judge if their personal interests are served in that way.
