The Holy Quran 30:5 — Surah Ar-Rum

Arabic text

بِنَصْرِ ٱللَّهِ ۚ يَنصُرُ مَن يَشَآءُ ۖ وَهُوَ ٱلْعَزِيزُ ٱلرَّحِيمُ

Translation

about (with) Allaah's assistance (because like the Mu'mineen, the Ahlul Kitaab were also monotheists, whereas the Persians were polytheists). Allaah assists whoever He wills (and will certainly assist the Muslims against the Mushrikeen), and He is the Mighty (none can defeat Him), the Most Merciful.

Tafsir (excerpt) — Tafsir Usmani

The prophecy comes true: that is, on that day there was, first, the joy of their own victory, and on top of it the further joy that the Romans, People of the Book (who were comparatively closer to the Muslims), prevailed over the Magians of Persia. People saw with their own eyes the truthfulness of the Quran's prophecy.
