4:78Wherever you may be, death will catch up with you, even if you were in fortified towers. When a good fortune comes their way, they say, “This is from God.” But when a misfortune befalls them, they say, “This is from you.” Say, “All is from God.” So what is the matter with these people, that they hardly understand a thing?

4:89They would love to see you disbelieve, just as they disbelieve, so you would become equal. So do not befriend any of them, unless they emigrate in the way of God. If they turn away, seize them and execute them wherever you may find them; and do not take from among them allies or supporters.

4:91You will find others who want security from you, and security from their own people. But whenever they are tempted into civil discord, they plunge into it. So if they do not withdraw from you, nor offer you peace, nor restrain their hands, seize them and execute them wherever you find them. Against these, We have given you clear authorization.
