Christian writers blamed imperial hubris for the Muslim conquest of Syria

Evidence

Heraclius’s defeat seems to be divine punishment not (this time) for heresy or sexual debauchery but for hubris. “Seduced,” after his victory over the Persians, “by the praise of his people who heaped the honor of victory not on God but on Heraclius himself he feared that rebuke which was being gravely presaged in his recurring visions.” For the emperor had recurring dreams of an invasion of rats from the desert and foresaw impending disaster in the course of the stars. — John V. Tolan, Saracens, 467
