2:13And when it is said to them, “Believe as the people have believed,” they say, “Shall we believe as the fools have believed?” In fact, it is they who are the fools, but they do not know.

2:89And when a scripture came to them from God, confirming what they have—although previously they were seeking victory against those who disbelieved—but when there came to them what they recognized, they disbelieved in it. So God’s curse is upon the disbelievers.

2:102And they followed what the devils taught during the reign of Salomon. It was not Solomon who disbelieved, but it was the devils who disbelieved. They taught the people witchcraft and what was revealed in Babylon to the two angels Harut and Marut. They did not teach anybody until they had said, “We are a test, so do not lose faith.” But they learned from them the means to cause separation between man and his wife. But they cannot harm anyone except with God's permission. And they learned what would harm them and not benefit them. Yet they knew that whoever deals in it will have no share in the Hereafter. Miserable is what they sold their souls for, if they only knew.

2:103Had they believed and been righteous, the reward from God would have been better, if they only knew.

2:109Many of the People of the Book wish to turn you back into unbelievers after you have believed, out of envy on their part, after the Truth has become clear to them. But pardon and overlook, until God brings His command. God has power over all things.

2:137If they believe in the same as you have believed in, then they have been guided. But if they turn away, then they are in schism. God will protect you against them; for He is the Hearer, the Knower.

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.

2:214Or do you expect to enter Paradise before the example of those who came before you had reached you? Adversity and hardship had afflicted them, and they were so shaken up, that the Messenger and those who believed with him said, “When is God’s victory?” Indeed, God’s victory is near.

2:218Those who believed, and those who migrated and fought for the sake of God—those look forward to God’s mercy. God is Forgiving and Merciful.

2:221Do not marry idolatresses, unless they have believed. A believing maid is better than an idolatress, even if you like her. And do not marry idolaters, unless they have believed. A believing servant is better than an idolater, even if you like him. These call to the Fire, but God calls to the Garden and to forgiveness, by His leave. He makes clear His communications to the people, that they may be mindful.

2:249When Saul set out with the troops, he said, “God will be testing you with a river. Whoever drinks from it does not belong with me. But whoever does not drink from it, does belong with me, except for whoever scoops up a little with his hand.” But they drank from it, except for a few of them. Then, when he crossed it, he and those who believed with him, they said, “We have no strength to face Goliath and his troops today.” But those who knew that they would meet God said, “How many a small group has defeated a large group by God’s will. God is with the steadfast.”

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.

2:260And when Abraham said, “My Lord, show me how You give life to the dead.” He said, “Have you not believed?” He said, “Yes, but to put my heart at ease.” He said, “Take four birds, and incline them to yourself, then place a part on each hill, then call to them; and they will come rushing to you. And know that God is Powerful and Wise.”

2:285The Messenger has believed in what was revealed to him from his Lord, as did the believers. They all have believed in God, and His angels, and His scriptures, and His messengers: “We make no distinction between any of His messengers.” And they say, “We hear and we obey. Your forgiveness, our Lord. To you is the destiny.”
