Firstly, there is a difference between a telescope and the prior advances that led to a telescope being invented. The telescope was not invented by a muslim scholar, hence that being why no one gives credit to one of them for that.

Secondly, to this claim:

> That's why there's little to no credit given to Muslim scholars (Arabic, Persian, Moorish Spain, etc) by the western scholars, by conveniently dismissing the Muslim golden era as "Dark Ages" but at the same time stealing the knowledge (idea, equations design, tools, etc) for most of the prior inventions by the Muslim scholars, for example the telescope.

From the link you provided, in the very first paragraph:

> The works of Alhazen were frequently cited during the Scientific Revolution by Galileo Galilei, René Descartes, Johannes Kepler, and Christiaan Huygens.

No credit or frequent credit - which is it?
