According to search-discovered classical Islamic scholarship, Quran 4:159 presents a profound eschatological prophecy regarding Prophet 'Isa (Jesus) and the People of the Book (Ahl al-Kitāb). The verse, 'And there is none from the People of the Scripture but that he will surely believe in him before his death,' has been the subject of deep analysis by major commentators. The central point of discussion, as explained by authorities like Ibn Kathir and Al-Tabari, revolves around the pronoun in 'before his death' (qabla mawtihi). The most widely held interpretation, narrated from Ibn Abbas, is that every Jew and Christian, at the moment of their own death, will see the truth and believe in 'Isa's real status as a prophet of Allah, but this forced belief at the point of despair holds no soteriological value. A second significant interpretation, supported by hadith, posits that the verse refers to the future, stating that after the second coming of 'Isa and before he eventually dies a natural death, all People of the Book alive on Earth will believe in him correctly, uniting under the banner of Islam. Both interpretations affirm the absolute certainty of 'Isa's true prophethood and serve as a divine statement on its ultimate, undeniable realization.
