Will someone who lived their life shunning sins and doing good deeds, then died as a non-Muslim, enter Paradise, or will they enter Hellfire due to not having embraced Islam?

If a person dies upon a religion other than Islam, then Paradise is forbidden for him, as Allah the Almighty says: "Indeed, whoever associates partners with Allah, Allah has forbidden him Paradise, and his refuge is the Fire." The good deeds performed by a disbeliever will not benefit him in the Hereafter, as Allah the Almighty says: "And whoever desires a religion other than Islam, it will never be accepted from him, and in the Hereafter, he will be among the losers," and His saying: "And We shall turn to whatever deeds they did, and We shall make them as scattered dust." The Prophet, peace and blessings be upon him, was asked about Ibn Jud'an, who used to do good deeds in the pre-Islamic era, and he replied that it would not benefit him because he never said, "My Lord, forgive me my sin on the Day of Judgment." As for the disbeliever whom the call of Islam did not reach, Allah the Almighty will test him on the Day of Resurrection.
