pretty sure that it was the Umayyads who converted Iran, not the Abbasids. For starters all the references I see to the fall of the Sassanid dynasty mention the Umayyad dynasty, and given the timeframe in which they fell, the Abbasids weren’t around yet.

I'm a couple of thousands kilometers away from the book, but according to what I remember from it, Umayyad's conquered Persia but the Persians stayed largely non-muslim for long time and the muslim population was mostly concentrated on several cities. So, most of the actual conversion happened during Abbasid time and it took decades if not centuries.
