5:47So let the people of the Gospel rule according to what God revealed in it. Those who do not rule according to what God revealed are the sinners.

5:59Say, “O People of the Scripture! Do you resent us only because we believe in God, and in what was revealed to us, and in what was revealed previously; and most of you are sinners?”

5:106O you who believe! When death approaches one of you, let two reliable persons from among you act as witnesses to the making of a bequest, or two persons from another people if you are travelling in the land and the event of death approaches you. Engage them after the prayer. If you have doubts, let them swear by God: “We will not sell our testimony for any price, even if he was a near relative, and we will not conceal God’s testimony, for then we would be sinners.”
