An-Nisa 4:76

Allatheena amanoo yuqatiloonafee sabeeli Allahi wallatheena kafaroo yuqatiloonafee sabeeli attaghooti faqatiloo awliyaaashshaytani inna kayda ashshaytanikana daAAeefa

Those who believe fight in the cause of Allāh, and those who disbelieve fight in the cause of ṭāghūt. So fight against the allies of Satan. Indeed, the plot of Satan has ever been weak.

The believers fight in the way of Allah, and the disbelievers fight in the way of Tāghūt. So, fight the friends of Satan. No doubt, the guile of Satan is feeble.
