And about English translation of hadith that mentioned in links in post #1.
I don't know what is Arabic word that used to call Heraclius in those hadith. But, use "Caesar" to call Heraclius in those English translated hadith is actually wrong. Heraclius was not Caesar but "Augustus" (emperor). Caesar as title was used to call Vice (or assistant of) Augustus.
