According to the unanimous consensus of classical Islamic scholarship, the concept of Al-Ākhirah (الآخرة), the Hereafter, represents the eternal and ultimate reality that follows this transient worldly life (al-Dunya). As a non-negotiable pillar of Islamic faith (Iman), it encompasses the resurrection, the Day of Judgment, and the final, everlasting abode in either Paradise (Jannah) or Hellfire (Jahannam). Ibn Kathir's tafsir on numerous Quranic verses emphasizes that this life is a test, with the results and ultimate justice being deferred to the Hereafter. The Arabic root meaning 'the last' or 'the end' underscores its finality. Al-Ghazali explains that a firm belief in the Hereafter is what gives a Muslim's life its moral and ethical direction, encouraging good deeds and patience with the knowledge that true reward is with Allah. This concept, mentioned over 100 times in the Quran, serves as the cornerstone of accountability, purpose, and divine justice in the Islamic worldview.
