Surah Rum Prophecies: Defeat & Victory Of Romans
١ الم
٢ غُلِبَتِ الرُّومُ
٣ فِي أَدْنَى الْأَرْضِ وَهُمْ مِنْ بَعْدِ غَلَبِهِمْ سَيَغْلِبُونَ
٤ فِي بِضْعِ سِنِينَ ۗ لِلَّهِ الْأَمْرُ مِنْ قَبْلُ وَمِنْ بَعْدُ ۚ وَيَوْمَئِذٍ يَفْرَحُ الْمُؤْمِنُونَ
Alif, Lam, Meem. The Romans have been defeated. In the nearer land; and they, after their defeat, will overcome. Within a few years. To Allah belonged the matter before and (to Him it belongs) thereafter. And on that day the believers will rejoice. Surah Rum 30:1-4
Historical Background
The Surah starts with a precise prediction that although the Romans have been defeated, but within a few years, they will again become victorious. The Surah here is referring to the Byzantine-Sassanid War of 602–628. When Emperor Maurice was killed by the usurper Phocas, Khosrau II waged war to revenge his death. Although the Persians were victorious during the first stages of the war, capturing much of the Egypt, Levant and even Anatolia. However, the coming to power of Heraclius ultimately drove to the Persians downfall.

Quran Miracle: Six Prophecies, Predictions and Scientific Facts
So this Surah actually gives six facts, miracles and predictions which fulfilled in a time span of 10-12 years. First is that Romans will be back and defeat their opponent which fulfilled starting from 623 AD with the initial victories of Romans and ends with the final defeat of Persians in the battle of Nineveh in 627AD. Second is “فِي أَدْنَى الْأَرْضِ” that is “in the nearer land” which actually proved right as these events happened in the regions much nearer to the region of Arabia. This word also includes another Miracle which you can see in “Miracle of Surah Rum: The Lowest Part of Earth” where you will come to know that in Arabic the literal meaning of أَدْنَى is low/ lowest and this battle where Romans were defeated happened in the regions of Dead Sea which we now come to know that it is the lowest region in the whole world (415 M below sea level).

Prediction Of Mecca Conquest
The other thing in verse is that Muslims will be happy that day: it is fulfilled by the rejoicing of Muslims on seeing the Quran’s claim and prediction coming true and their opponent’s claims turning wrong. Fourth: the same time Muslims won their first battle of Badr in 623AD at the start of Romans victories and then in 628AD Muslims conquered Mecca after Romans decisively defeated Persians in the battle of Nineveh in 627AD.
Miracle Of Universal Application

Fifth if we consider the entire Universe, even then these verses should prove right in the same way. The only thing that comes in mind immediately is whether this planet Earth fulfills the verdict of verse 2 of this Surah. For this it should pass the test of both the meanings that the word “أَدْنَى” has within it. Now as for the first meaning of أَدْنَى “Nearest,” for us humans, this planet Earth is and always be the nearest place because it is our birthplace. Now for the second meaning “Lowest” we need to understand again that on macro scale on this Universe everything is relative and because we humans beings have originated on planet Earth and from here wherever we see or go in this Universe mathematically our st
