Will the disbelieving scholars who rendered services beneficial to humanity—such as Einstein—and died outside of Islam, be rewarded for their deeds on the Day of Judgment?

Faith is a prerequisite for the acceptance of deeds and their reward. The disbeliever is not rewarded for his good deeds in the Hereafter, as Allah, the Exalted, clarified: "And nothing prevented their contributions from being accepted from them except that they disbelieved in Allah and in His Messenger." Nevertheless, Allah rewards him for his good in this world. As for the believer, Allah saves his good deeds for him in the Hereafter and provides for him in this world due to his obedience.
