2:88And they said, “Our hearts are sealed.” Rather, God has cursed them for their ingratitude. They have little faith.

2:93And We made a covenant with you, and raised the Mount above you: “Take what We have given you firmly, and listen.” They said, “We hear and disobey.” And their hearts became filled with the love of the calf because of their disbelief. Say, “Wretched is what your faith commands you to do, if you are believers.”

2:98Whoever is hostile to God, and His angels, and His messengers, and Gabriel, and Michael—God is hostile to the faithless.

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.

2:108Or do you want to question your Messenger as Moses was questioned before? Whoever exchanges faith for disbelief has strayed from the right path.

2:143Thus We made you a moderate community, that you may be witnesses to humanity, and that the Messenger may be a witness to you. We only established the direction of prayer, which you once followed, that We may distinguish those who follow the Messenger from those who turn on their heels. It is indeed difficult, except for those whom God has guided. But God would never let your faith go to waste. God is Kind towards the people, Merciful.

2:161But as for those who reject faith, and die rejecting—those—upon them is the curse of God, and of the angels, and of all humanity.

2:186And when My servants ask you about Me, I Am near; I answer the call of the caller when he calls on Me. So let them answer Me, and have faith in Me, that they may be rightly guided.

2:250And when they confronted Goliath and his troops, they said, “Our Lord, pour down patience on us, and strengthen our foothold, and support us against the faithless people.”
