Fighting

Except for those who seek refuge with a people bound to you by a treaty, or those who come to you with hearts unwilling to fight either you or their own people. Had Allah willed, He could have empowered them against you, and they would have fought you. So, if they withdraw, refuse to fight, and offer peace, then Allah does not permit you to harm them.

4:90Except those who seek refuge with a people between whom and you there is a covenant, or (those who) come unto you because their hearts forbid them to make war on you or make war on their own folk. Had Allah willed He could have given them power over you so that assuredly they would have fought you. So, if they hold aloof from you and wage not war against you and offer you peace, Allah alloweth you no way against them.
