Thank you gerdbonk.
Just found your TAM9 album, if you are going to TAM this year, please follow me around, with camera in tow.
I might just need you to look over my long photo needs list. From time to time I will do a shout out on FB asking for specific photos needed for WP pages.
If you would be so kind I would like to have this one.

Don't want to get off topic (too late)
Graham2001
so seriously you want to improve this page?
http://en.wikipedia.org/wiki/Ibn_Farrukh
What a nightmare!
Not even sure why this page still exists on WP? Probably because there are too few people trying to repair WP and too many wanting to just throw things on WP without citations.
If you really really want to do this rewrite then there are several ways to do so.
First write on the talk page your intentions so that you don't have some other editor coming out of the walls to freak out on you. I doubt this will happen as it is like the great-great-grandniece of a stub page. But it is still the polite thing to do.
Then you need to find real citations (not the blog) but surely they used some kind of citations (sorry I didn't read it).
Generally you will become a expert (of sorts) on this topic.
There are many ways to do this, depends on how you like to organize things. My team prefers to work using their sandbox or a user page. This way no one will mess with your changes as you are not making the work-in-progress public.
You will need to read all you can find on the subject. Keep track of all the citations. These should be notable citations (notable usually means they have their own WP page, but not always)
You will not write it like a essay, but it will have at least 1-3 paragraphs explaining what the page is about (this is your lede or sometimes called a lead)
Then you will have the body of the article to explain more in detail what you said in the lede. Everything in the body, every single claim you make must be cited.
Then you have to finish up the article with all the nuts and bolts that make the page better, categories, external links, reference area and so on. I suggest you look around the hoaxs category
http://en.wikipedia.org/wiki/Category:Hoaxes and any other pages that might be peers. See how they are handled, and learn from what they have done/not done.
You are always welcome to run it past me by email
susangerbic@yahoo.com as I rarely check JREF these days.
So, because you said you already edit WP I won't go into the major details on how to do this. I'm just going to assume you meant that when you wrote "but am not sure how to proceed in this case." you mean, where do I start? Not, "how do I do this?"
There are many talented people here on this forum, and I'm sure they will advise you as you go along.
