Will the righteous disbelievers go to Hell?


There are many Christians who do lots of excellent charity work and are generally very righteous people. Will these go to Hell according to the Quran?


Before replying to this question, it is necessary to state that only God knows the content of the hearts and who is a believer and who is not. We do not know the content of the hearts nor are we the ones who will judge.
All that can be said is what the Quran says about the fate of the disbelievers on Judgement Day, then the matter is in God’s hands alone.
We read a number of verses in the Quran which state that all the good works of the disbelievers are nullified on Judgement Day and count for nothing:

Any of you who revert from his religion and die as disbelievers, for those,
their works are nullified in this world and in the Hereafter, and these are the companions of the Fire, therein they shall permanently remain. 2:217

Those who deny Our revelations and the meeting of the Hereafter,
their works are nullified. Are they being repaid except for what they used to do? 7:147

The example of those who disbelieved in their Lord is that their works are like ashes in a strong wind on a stormy day. They are unable to gain anything from what they earned; such is the farthest straying. 14:18

They are the ones who disbelieved in the revelations of their Lord and in His meeting, thus,
their works were nullified, and so We assign no weight for them on the Day of Resurrection. 18:105
