5:23Two men of those who feared, but whom God had blessed, said, “Go at them by the gate; and when you have entered it, you will prevail. And put your trust in God, if you are believers.”

5:27And relate to them the true story of Adam's two sons: when they offered an offering, and it was accepted from one of them, but it was not accepted from the other. He Said, “I will kill you.” He Said, “God accepts only from the righteous.”

5:95O you who believe! do not kill game while you are in pilgrim sanctity. Whoever of you kills any intentionally, its penalty shall be a domestic animal comparable to what he killed, as determined by two honest persons among you—an offering delivered to the Kaabah. Or he may atone by feeding the needy, or its equivalent in fasting, so that he may taste the consequences of his conduct. God forgives what is past. But whoever repeats, God will take revenge on him. God is Almighty, Avenger.

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.”

5:107If it is discovered that they are guilty of perjury: let two others take their place, two from among those responsible for the claim, and have them swear by God, “Our testimony is more truthful than their testimony, and we will not be biased, for then we would be wrongdoers.”
