5:8O you who believe! Be upright to God, witnessing with justice; and let not the hatred of a certain people prevent you from acting justly. Adhere to justice, for that is nearer to piety; and fear God. God is informed of what you do.

5:13Because of their breaking their pledge, We cursed them, and made their hearts hard. They twist the words out of their context, and they disregarded some of what they were reminded of.

5:44We have revealed the Torah, wherein is guidance and light. The submissive prophets ruled the Jews according to it, so did the rabbis and the scholars, as they were required to protect God’s Book, and were witnesses to it. So do not fear people, but fear Me. And do not sell My revelations for a cheap price. Those who do not rule according to what God revealed are the unbelievers.

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.”

5:111“And when I inspired the disciples: `Believe in Me and in My Messenger.' They said, `We have believed, so bear witness that We have submitted.'“

5:113They said, “We wish to eat from it, so that our hearts may be reassured, and know that you have told us the truth, and be among those who witness it.”

5:117I only told them what You commanded me: that you shall worship God, my Lord and your Lord. And I was a witness over them while I was among them; but when You took me to Yourself, you became the Watcher over them—You are Witness over everything.
