The Arabic wordtaghut or taaghoot ( ar. طاغوت, ṭāġūt, pl. ṭawāġīt) means to "cross the limits, overstep boundaries," or "to rebel." In Islamic theology, the word refers to idolatry or to the worship of anything except Allah.
Taghut also denotes one who exceed their limits. The first stage of error is fisq (i.e. disobeying God without denying that one should obey Him), the second is kufr, (i.e. rejection of the very idea that one should obey God). The last stage would be not only to rebel against God but also impose their rebellion against the will of God upon others. Those who reach this stage are taghut.
