Fighting

Indeed, those who turned away on the day the two armies met were made to slip by Satan due to their past deeds. But Allah has forgiven them.

3:155Lo! those of you who turned back on the day when the two hosts met, Satan alone it was who caused them to backslide, because of some of that which they have earned. Now Allah hath forgiven them. Lo! Allah is Forgiving, Clement.

It is Satan who instills fear in his allies, do not fear them, but fear Me if you are true believers.

3:175It is only the devil who would make (men) fear his partisans. Fear them not; fear Me, if ye are true believers.

So, battle against the allies of Satan; his schemes are weak.

4:76Those who believe do battle for the cause of Allah; and those who disbelieve do battle for the cause of idols. So fight the minions of the devil. Lo! the devil's strategy is ever weak.
