Here are some verses from just the second and third books of the Quran which say that Hell is reserved for Christians and Jews. There is a lot more in the rest of the Quran,:
2:135. And they say, “Be Jews or Christians, and you will be guided.” Say, “Rather, the religion of Abraham, the Monotheist; he was not an idolater.”
2:120. The Jews and the Christians will not approve of you, unless you follow their creed. Say, “Allah’s guidance is the guidance.” Should you follow their desires, after the knowledge that has come to you, you will have in Allah neither guardian nor helper.
2:140. Or do you say that Abraham, Ishmael, Isaac, Jacob, and the Patriarchs were Jews or Christians? Say, “Do you know better, or Allah?” And who does greater wrong than he who conceals a testimony he has from Allah? Allah is not unaware of what you do.
3:151. We will throw terror into the hearts of those who disbelieve, because they attribute to Allah partners [the Trinity] for which He revealed no sanction. Their lodging is the Fire. Miserable is the lodging of the evildoers.
2:165. Yet among the people are those who take other than Allah as equals to Him [the Trinity]. They love them as the love of Allah. But those who believe have greater love for Allah. If only the wrongdoers would realize, when they see the torment; that all power is Allah’s, and that Allah is severe in punishment.
3:18. Allah bears witness that there is no god but He, as do the angels, and those endowed with knowledge—upholding justice. There is no god but He, the Mighty, the Wise.
3:19. Religion with Allah is Islam. Those to whom the Scripture was given differed only after knowledge came to them, out of envy among themselves. Whoever rejects the signs of Allah—Allah is quick to take account.
3:85. Whoever seeks other than Islam as a religion, it will not be accepted from him, and in the Hereafter he will be among the losers.
3:102. O you who believe! Revere Allah with due reverence, and do not die except as Muslims.
3: 91. As for those who disbelieve and die disbelievers, even the earth full of gold would not be accepted from any of them, were he to offer it for ransom. These will have a painful torment, and will have no saviors.
3:10. As for those who disbelieve, neither their wealth nor their children will avail them anything against Allah. These will be fuel for the Fire.
3:12. Say to those who disbelieve, “You will be defeated, and rounded up into Hell—an awful resting-place.”
3:116. As for those who disbelieve, neither their possessions nor their children will avail them anything against Allah. These are the inhabitants of the Fire, abiding therein forever.
3:176. And do not be saddened by those who rush into disbelief. They will not harm Allah in the least. Allah desires to give them no share in the Hereafter. A terrible torment awaits them.
2: 126. When Abraham said, “O My Lord, make this a peaceful land, and provide its people with fruits—whoever of them believes in Allah and the Last Day.” He [Allah] said, “And whoever disbelieves, I will give him a little enjoyment, then I will consign him to the punishment of the Fire; how miserable the destiny!”
2: 206. And when he is told, “Beware of Allah,” his pride leads him to more sin. Hell is enough for him—a dreadful abode.
3:28. Believers are not to take disbelievers for friends instead of believers. Whoever does that has nothing to do with Allah, unless it is to protect your own selves against them. Allah warns you to beware of Him. To Allah is the destiny.
2:135. And they say, “Be Jews or Christians, and you will be guided.” Say, “Rather, the religion of Abraham, the Monotheist; he was not an idolater.”
