Why does it lead by describing him as a Muslim? I don't see anything else in the article that refers to that - he's not noted as a Imam or a Koran scholar or anything similar. Wouldn't it make more sense to simply say he was from an area that today is Turkey?
Not sure what Turkey has to do with him. But it makes sense to attribute someone to country/empire at the time he lived in. Which is the Islamic Empire. So saying he was Muslim, is as much as saying a scientist today residing in the US is American.
Contrary to popular western belief, Islam is one of the main enablers for these great scientists... as many were "influenced by the Quranic injunctions and hadiths, such as "the ink of a scholar is more holy than the blood of a martyr," that stressed the value of knowledge.'" But more than that, is the amount of government funding and salaries these guys would get (in some cases, what would amount to today's pro athletes').

I think it's using 'Muslim' as an ethnicity, which is of course incorrect. This would explain why his religious stuff isn't noted anywhere else. I encourage you to amend the article :-)
