3:77Those who exchange the covenant of God, and their vows, for a small price, will have no share in the Hereafter, and God will not speak to them, nor will He look at them on the Day of Resurrection, nor will He purify them. They will have a painful punishment.

3:81God received the covenant of the prophets, “Inasmuch as I have given you of scripture and wisdom; should a messenger come to you verifying what you have, you shall believe in him, and support him.” He said, “Do you affirm My covenant and take it upon yourselves?” They said, “We affirm it.” He said, “Then bear witness, and I am with you among the witnesses.”

3:183Those who said, “God has made a covenant with us, that we shall not believe in any messenger unless he brings us an offering to be consumed by fire.” Say, “Messengers have come to you before me with proofs, and with what you asked for; so why did you assassinate them, if you are truthful?”
