At the time when Islam appeared, humanity was drowning in the mire of ignorance, injustice, and corruption, and human relations were mostly based on conquest, conflict, oppression, and enslavement. Islam came as a mercy to the worlds, to save humanity and restore to man his lost humanity, his lost dignity, and his violated rights. It announced to the people that they are of common descend, They are equal in creation, and no one has superiority over the other except through piety. He called on them to worship the Lord of servants, and to justice, benevolence, peace, security, forgiveness, tolerance, good morals, good neighborliness, refraining from harm, and rejecting injustice and aggression.From this standpoint, Islam has based the relationship of Muslims with non-Muslims on peace and security, not on war and fighting, and it acknowledges that the legitimacy of war and fighting depends on repulsing aggression, warding off strife, or protecting and supporting the oppressed. The basis of its legitimacy is based on the principle of necessity, which is a self-compulsive matter that Muslims resort to under necessity. God Almighty said: Fighting has been made obligatory upon you believers, though you dislike it. [Al-Baqarah / 216], which indicates that the position of Muslims regarding peace or war depends on the position of others. The rule is that Muslims are at peace with those who are at peace with them, and war is against those who fight them. As for jihad, it is more comprehensive than limiting it to fighting only. It is striving and exerting effort to uphold the word of God Almighty, and its goal is to bring people out of the darkness of ignorance and disbelief into the light of faith, purify the homelands from the filth of occupation and colonialism, defend values and sanctities, and repel injustice, aggression and tyranny.
