هرقل ومحمد ﷺ

Abu Sufyan admitted that Muhammad was nobleman of impeccable honesty, preached strict monotheism (Tawhid), commanded social justice, and that his followers never abandoned his faith.

Upon hearing this, Heraclius recognized the scriptural patterns of historical prophethood and made his famous declaration:

“If what you say is true, he will soon conquer the ground beneath my very feet.”

Heraclius’s prediction unfolded across the Levant. Following the decisive Battle of Yarmouk in 636 CE, Byzantine control over Syria, Palestine, and Egypt permanently dissolved. In 637–638 CE, Jerusalem surrendered peacefully to Caliph Umar.

Heraclius passed away on February 11, 641 CE in Constantinople as a broken leader, having watched the southern half of his empire—including the Levant, Palestine, and Egypt—slip permanently from Byzantine control during his final years.

Note: The Muslims won the Battle of Nahavand in 642 CE, which broke the last organized Sasanian army shortly after Emperor Heraclius’s death and marked the decisive fall of the Persian Empire.
