salam to all of you i am just wondering as we say israel is occupying,doing brutal actions and likewise america invade to different countries and rob their all resources it is must not happen.but i want to know why muslim invaded to spain and subcontinent and different parts of the world.was that right,and did any shia muslim supported that kind of conquests? if yes why did they supported.because it is absolutely unacceptable to go and fight with those who have nothing to do with you.and are not harming you.Does anyone can suggest any good book on that topic.
