2:72And recall when you killed a person, and disputed in the matter; but God was to expose what you were hiding.

2:76And when they come across those who believe, they say, “We believe,” but when they come together privately, they say, “Will you inform them of what God has disclosed to you, so that they might dispute with you concerning it before your Lord?” Do you not understand?

2:213Humanity used to be one community; then God sent the prophets, bringing good news and giving warnings. And He sent down with them the Scripture, with the truth, to judge between people regarding their differences. But none differed over it except those who were given it—after the proofs had come to them—out of mutual envy between them. Then God guided those who believed to the truth they had disputed, in accordance with His will. God guides whom He wills to a straight path.

2:253These messengers: We gave some advantage over others. To some of them God spoke directly, and some He raised in rank. We gave Jesus son of Mary the clear miracles, and We strengthened him with the Holy Spirit. Had God willed, those who succeeded them would not have fought one another, after the clear signs had come to them; but they disputed; some of them believed, and some of them disbelieved. Had God willed, they would not have fought one another; but God does whatever He desires.
