`   Sources that his father was Magi? He himself was a Sunni Muslim(it's not debated)...weird, no? Actually, your logic says that everyone who wrote in Arabic is under suspicion of being a Persian untill proven otherwise, is self-contradictory. I'm an Arab, is my ethnicity under suspicion because I talk, write, and think in Arabic? Very self-contradictory indeed. Also, what's this about there being no debate about him being Persian? Who are these ``informed Islamic scholars``? Their names? Sources where they said that he was Persian? Give me tangible proof...untill then, he's obviously an Arab by the bulk of evidence and sources I gave.  `
