An-Nisá 4:90 الا الذين يصلون الى قوم بينكم وبينهم ميثاق او جاءوكم حصرت صدورهم ان يقاتلوكم او يقاتلوا قومهم ولو شاء الله لسلطهم عليكم فلقاتلوكم فان اعتزلوكم فلم يقاتلوكم والقوا اليكم السلم فما جعل الله لكم عليهم سبيلا ٩٠

Except 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.

Except those who join a group between whom and you there is a treaty (of peace), or those who approach you with hearts restraining them from fighting you as well as fighting 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 (instead) send you (Guarantees of) peace, then Allah Hath opened no way for you (to war against them).
