They are those with whom thou didst make a covenant, but they break their covenant every time, and they have not the fear (of God). (8:56)

Those who believed, and adopted exile, and fought for the Faith, with their property and their persons, in the cause of God, as well as those who gave (them) asylum and aid,- these are (all) friends and protectors, one of another. As to those who believed but came not into exile, ye owe no duty of protection to them until they come into exile; but if they seek your aid in religion, it is your duty to help them, except against a people with whom ye have a treaty of mutual alliance. And (remember) God seeth all that ye do. (8:72)

(But the treaties are) not dissolved with those Pagans with whom ye have entered into alliance and who have not subsequently failed you in aught, nor aided any one against you. So fulfil your engagements with them to the end of their term: for God loveth the righteous. (9:4)

How can there be a league, before God and His Apostle, with the Pagans, except those with whom ye made a treaty near the sacred Mosque? As long as these stand true to you, stand ye true to them: for God doth love the righteous. (9:7)
