Fitna (word)

Fitna (فتنة) is an Arabic word for wrongdoing. The word also includes the idea of drawing someone away from God.

The term is often used for the First Islamic civil war, in 656–661 CE, a prolonged struggle for the caliphate after the 656 assassination of the caliph Uthman ibn Affan. The Second Fitna, or Second Islamic civil war, is usually identified as the 683–685 CE conflict among the Umayyads for control of the caliphate.

It is also used for non-believers.

Qur'an 8:39 "So fight them until there is no more Fitnah (disbelief [non-Muslims]) and all submit to the religion of Allah alone (in the whole world)."
Qur'an 8:40 "If people are obstinate, and refuse to surrender, know Allah is your Supporter."

Another translation omits this Arabic term: [8.38] Say to those who disbelieve, if they desist, that which is past shall be forgiven to them; and if they return, then what happened to the ancients has already passed. [8.39] And fight with them until there is no more persecution and religion should be only for Allah; but if they desist, then surely Allah sees what they do.
