According to search-discovered classical Islamic scholarship, the mention of the Byzantines (Ar-Rum) in the Quran, specifically in Surah Ar-Rum, serves as a profound historical and theological signpost. Ibn Kathir explains that the verses refer to the Byzantine-Sasanian War, where the Christian Byzantines were initially defeated by the Zoroastrian Persians. The Quran then makes a stunning prophecy that the defeated Byzantines would be victorious 'in a few years.' Al-Qurtubi highlights the wisdom in this prophecy, noting it as a clear proof of the Quran's divine origin, revealed at a time when a Byzantine recovery seemed impossible. This event was not merely a political forecast; its fulfillment deeply strengthened the faith of the early Muslims, who saw the victory of a fellow monotheistic people as a sign of God's support. The synthesis of historical events with Quranic revelation on the Byzantines demonstrates God's absolute sovereignty over the rise and fall of empires and provides an enduring lesson on the truth of divine promises.
