The Quran accurately predicted the Roman Empire's victory over the Persians within a few years, proving Muhammad's prophethood.

The Quran states in Surah 30:2-4 that the Roman Empire would be defeated but would soon be victorious within a 'few years.' However, the term 'few years' in Arabic, according to Yusuf Ali, refers to a period of three to nine years. Historical evidence indicates that the Byzantine victory over the Persians did not occur until approximately fourteen years later, which contradicts the Quranic prophecy. Renowned historian al-Tabari also places the Roman victory in 628 A.D., which aligns with the historical timeline but does not fulfill the prophecy's timeframe. Furthermore, the events surrounding the Roman victory, including the assassination of the Persian emperor and the subsequent peace negotiations, further illustrate the inaccuracy of the claim that the prophecy was fulfilled as stated in the Quran. Thus, based on the biblical test for prophets found in Deuteronomy 18:20-22, Muhammad's prophecy fails to meet the criteria for a true prophet.
