Prophet Hud - 11:116 Should not the righteous of the generations before you have prevented evil in the earth? Except a few whom We saved from them. As for the wrongdoers, they indulged in the prosperity given to them, so they joined the criminals.
Oppressors and aggressors on the earth must be opposed:
The Table Spread/5:61 "When they came to you, they said: "We believe". But they entered you with their disbelief and left you with their disbelief. Allah knows better what they conceal."
The Table Spread/5:62 You see most of them running about in sin and enmity and forbidden food. How evil is what they do!
The Table Spread/5:63 Should not their rabbis and their clergymen have forbidden them from speaking sinful words and eating unlawful food? How wicked what they do!

The Cow/2:246 "Did not this incident attract your attention? The elders of the Children of Israel said to one of their prophets after Moses, "Appoint us a king so that we may fight for the cause of Allah. He said, "What if war is necessary and you do not fight?"They replied, "Why should we not fight in the cause of Allah when we are driven away from our homes and our children?"But when war was obligatory upon them, they turned away except a few. Allah Knows the wrongdoers."
The Cow/2:279 If you do not do so, expect a war from Allah and His Messenger. If you repent, your principal is yours again. Do not be wronged nor be wronged.

The Women/4:75 "What has happened to you that you do not fight in the way of Allah, despite the oppressed men, women and children who cry out, "Our Lord, deliver us from this land whose people are oppressors, protect us, help us"?"

Prophet Hud/11:116 Should not the righteous of the generations before you have prevented evil in the earth? Except a few whom We saved from them. As for the wrongdoers, they indulged in the prosperity given to them, so they joined the criminals.

The Pilgrimage/22:39 Permission has been granted to those who were wronged and war was waged against them. Allah is surely able to support them.
The Pilgrimage/22:40 "Those who were unjustly expelled from their land only because they said: "Our Lord is Allah". If Allah had not defended some of the people against others, the monasteries, churches, synagogues and masjids in which Allah´s Name is much mentioned would have been destroyed. Allah will surely help those who help Him. Allah is Mighty, Powerful,"

Council/42:42 But those who oppress the people and those who attack unjustly in the land should be opposed. For them is a painful torment.

The Woman Who Is Examined/60:8 Allah does not forbid you to do good to those who do not fight you for the sake of religion and do not drive you out of your homes, and to do justice to them. Allah loves those who do justice.
The Woman Who Is Examined/60:9 But Allah forbids you to be friends only with those who fight you in the cause of religion and drive you out of your homes and help you to be driven out. Those who take them as friends are wrongdoers.
