I'm pretty sure that's correct but I'm not 100% sure it was the "Toledo School" of translators in Andalusia or Gerard of Cremona.
There are several popular historical books on this available, including "The House of Wisdom" and "Aladdin's Lamp" etc. Some are better than others.
I looked a lot of this up when I was writing an article on the "Studia Arabum" - a collection of great works written in Arabic (and Persian) that was unknown in the Western world until translated back from Arabic in Iberia in the 13th century. It included a whole lot of Greek works otherwise thought lost - sort of a "Who's Who in Philosophy II" to pad out the Appendix in Art & Academe.
The only thing to come out of this so far is the Index of Books by Ability in the official line (up to HMRE, posted on the Atlas website):
atlas-games.com/pdf_storage/ ... yIndex.pdf
(yes it was a lot of work, no the book rules don't really have the granularity to do medieval science justice but then they're complex enough as it is, yes I am insane to do the index)
I still have the article draft but checking through it, I didn't get to Alhazen but did Alkind, Al Khwarizmi, more Adelard and various others. (Alhazen's pretty cool and I wanted to include him).
Alkindi's (c.801-c.873) contribution would be:
Kitab al-Shu'a'at (Book of the Rays), an Arabic tractatus on optics. Philosophiae (natural philosophy), Quality 10.
I had a thought about several of the books secretly being translated by Hermetic magi in a covenant hidden within the university...
PS BTW, as the Quality of a mundane book is dependent on the author's Com and possession of the Good Teacher Virtue, and independent of the authors actual Ability score (apart from needing a minimum to write on the topic), it's quite easy to create books, especially tractati. Summae are similar, although Level is determined by author Ability score unless you choose to "dumb it down" to make things clearer (improve Quality but reduce Level). Most medieval books are tractati or collections of tractati (and/or encyclopedias) if you read their real world descriptions, particularly as "book" is often used loosely for what we would consider a chapter. If you can guesstimate whether a given author was say better at communicating his message than Averroes but less of a writer than Cicero, you can generate a Quality score easily enough (see table below which won;t come out very well but is in the Excel file).
Alhazen may have more insights than Alkindi but if he couldn't write to save himself, his tractati may be of lower quality regardless of whether he had a Philosophiae (natural philosophy) score of 12+ and a summae written by him may be comprehensive but not necessarily better than reading a whole lot of high Quality tractati, particulalry if you've already got a decent Ability score of 6+. Of course tractati may contain special insights, facts etc that may be of use beyond their value as an XP provider - maybe even the secret of a Minor Virtue that would add some different Guidelines to optic related Imaginem spells etc.
