If anyone else has trouble with the spellings of the names (which, for the most part, are transliterated from Arabic or Urdu or Farsi or some other language and have many multiple spellings), please let me know what you typed in and I can add those as alternates as well.
I think the clue for al-Razi can be improved; I knew who he was but there are so many persian muslim polymaths it wasn't very specific. I tried al-khwarezmi and al-Kindi among others. He was most famous for being a physician, and he was also better known as Abu-Bakr rather than Muhammad.
Alternatively, you could mentioned that he is known in the west as Rhazes.
