[2:190] You may fight in the cause of GOD against those who attack you, but do not aggress. GOD does not love the aggressors.
*2:190 All fighting is regulated by the basic rule in 60:8-9. Fighting is allowed strictly in self-defense, while aggression and oppression are strongly condemned throughout the Quran.

[6:151] Say, "Come let me tell you what your Lord has really prohibited for you: You shall not set up idols besides Him. You shall honor your parents. You shall not kill your children from fear of poverty - we provide for you and for them. You shall not commit gross sins, obvious or hidden. You shall not kill - GOD has made life sacred - except in the course of justice. These are His commandments to you, that you may understand."
