4:90Except those who join people with whom you have a treaty, or those who come to you reluctant to fight you or fight their own people. Had God willed, He would have given them power over you, and they would have fought you. If they withdraw from you, and do not fight you, and offer you peace, then God assigns no excuse for you against them.

4:165Messengers delivering good news, and bringing warnings; so that people may have no excuse before God after the coming of the messengers. God is Powerful and Wise.
