In Islam, one's condition in the afterlife, whether in heaven or hell, is determined by the degree to which one has affirmed the unity and justice of God, acted with mercy and justice toward others, and been ethically responsible. Heaven will be achieved by those who have faith in God's revelations and have lived out that faith through their good works and moral conduct. Unbelievers and evildoers will be punished eternally in hell. Every individual will be held accountable for his or her own actions on the Day of Judgment. In the twentieth century, discussions about the afterlife address the interconnection between human action and divine judgment, the need for moral rectitude, and the eternal consequences of human action in this life and world.
