Fight for the sake of God those that fight against you, but do not attack them first. God does not love the aggressors.
Slay them wherever you find them. Drive them out of the places from which they drove you. Idolatry is worse than carnage.
Quran 2:190-2:191, "The Cow," Dawood, p. 28
When the sacred months are over slay the idolaters wherever you find them. Arrest them, besiege them, and lie in ambush everywhere for them.
Quran 9:5; "Repentance," Dawood, p. 186
Prophet, make war on the unbelievers and the hypocrites and deal rigorously with them. Hell shall be their home: an evil fate.
Quran 9:73, "Repentance," Dawood, p. 198
