Regarding "possible place of birth": Do not link, and ..., in my opinion[change source]
From English wiki:
"His birthplace could have been Fārāb on the Jaxartes (Syr Darya) in modern Kazakhstan, or maybe Fāryāb in Greater Khorasan (modern day Afghanistan). The older Persian[1] Pārāb (in Ḥudūd al-ʿĀlam) or Fāryāb (also Pāryāb), is a common Persian toponym meaning "lands irrigated by diversion of river water".[2][3] By the 13th century, Fārāb on the Jaxartes was known as Otrār.[4]
Scholars largely agree that Farabi's ethnic background is not knowable.[1][5][6][7][8]"
Comment - The place of birth, is quite probably, one (of many places a called Farab).
"Farab" should not be "blue linked" or "red linked".
"Farab" should be followed by a set of parenthesis, with text that might say "(research has not shown, exactly which place called "Farab", where he possibly was born ...)".
