Will non-Muslims be equal in recompense on the Day of Judgment, despite the difference in their deeds, good and bad, in this world?

Allah rewards the disbeliever in this world for his good deeds, and he will have no share in the Hereafter, as the Prophet (peace be upon him) said: "Indeed, Allah does not wrong a believer concerning a good deed; he is given for it in this world and rewarded for it in the Hereafter. As for the disbeliever, he is given for the good deeds he did for Allah Almighty in this world, until when he is brought to the Hereafter, he has no good deed for which to be rewarded."

Al-Nawawi said: "Scholars have unanimously agreed that a disbeliever who died upon disbelief will have no reward in the Hereafter and will not be recompensed for any of his deeds in this world."

Disbelievers are not equal in the Hereafter; some of them will have a more severe punishment depending on their disbelief, injustice, or their call to worship themselves.
