Except those who join a group that has an understanding (of peace) with you, or those who approach you with their hearts not willing to fight you and also not willing to fight their own people. If Allah had pleased, He could have given them power over you, and they would have fought you therefore if they withdraw from you, but fight you not, and (they also) send you (assurances of) peace, then Allah has opened no way for you (to war against them).
