Assalaam Alaikum Wa Rahmatullahi Wa Barakatuh,
We should just tell the reality of Quran as much as possible.
Islam teaches peace.According to Qur'an killing an innocent person is like killing all humanity.A real Muslim cannot be a terrorist. Qur'an never justifies killing even just one innocent person.
"If any one slew a person -unless it be for murder or for spreading mischief in the land- it would be as if he slew the whole people," Qur’an, 5:32
the rights of an innocent man cannot be cancelled for the sake of all the people. A single individual may not be sacrificed for the good of all. In the view of Almighty Allah's compassion, right is right, there is no difference between great and small. The small may not be annulled for the great. Without his consent, the life and rights of an individual may not be sacrificed for the good of the community. If he consents to sacrifice them in the name of patriotism, that is a different matter.
