Would ye question your Apostle as Moses was questioned of old? but whoever changeth from Faith to Unbelief, Hath strayed without doubt from the even way. (2:108)

When Jesus found Unbelief on their part He said: "Who will be My helpers to (the work of) God?" Said the disciples: "We are God's helpers: We believe in God, and do thou bear witness that we are Muslims. (3:52)

Nor would he instruct you to take angels and prophets for Lords and patrons. What! would he bid you to unbelief after ye have bowed your will (To God in Islam)? (3:80)

And the Hypocrites also. These were told: "Come, fight in the way of God, or (at least) drive (The foe from your city)." They said: "Had we known how to fight, we should certainly have followed you." They were that day nearer to Unbelief than to Faith, saying with their lips what was not in their hearts but God hath full knowledge of all they conceal. (3:167)

Those who purchase Unbelief at the price of faith,- not the least harm will they do to God, but they will have a grievous punishment. (3:177)

Verily the transposing (of a prohibited month) is an addition to Unbelief: the Unbelievers are led to wrong thereby: for they make it lawful one year, and forbidden another year, in order to adjust the number of months forbidden by God and make such forbidden ones lawful. The evil of their course seems pleasing to them. But God guideth not those who reject Faith. (9:37)

They swear by God that they said nothing (evil), but indeed they uttered blasphemy, and they did it after accepting Islam; and they meditated a plot which they were unable to carry out: this revenge of theirs was (their) only return for the bounty with which God and His Apostle had enriched them! If they repent, it will be best for them; but if they turn back (to their evil ways), God will punish them with a grievous penalty in this life and in the Hereafter: They shall have none on earth to protect or help them. (9:74)
