Surah Ar-Rum Verse 3

3506 The Pagan Quraysh of Makkah rejoiced at the overthrow of Rome by Persia . They were pro-Persian. and in their heart of hearts they hoped that the nascent movement of Islam, which at that time was, from a worldly point of view, very weak and helpless, would also collapse under their persecution. But they misread the true Signs of the times. They are told here that they would soon be disillusioned in both their calculations, and it actually so happened at the battle of Issus in 622 A.C. (the year of Hijrah) and in 624 A.C., when Heraclius carried his campaign into the heart of Persia (see Appendix VIII) and the Makkan Quraysh were beaten off at Badr.
