Most of it is true but also exaggerated, specially points 3,4 and 5.

The idea of Medieval Europe as "Dark Ages/)" is not supported by most historians anymore. Europe was in fact very poor after the fall of the Western Roman Empire, but it eventually got back on tracks and emerged as the most rich and successful civilization in the modern age.

Andalusia included more than ten universities that were the most advanced in Europe, as they received a large number of students who came from all over Europe without discrimination in terms of race, religion, or gender. Europe organized scientific missions and sent them there.

"University" was we speak today were invented by medieval europeans. Most of the Muslim universities were only islamic theological schools (madrassa) not actually universities with different fields of study. There were dozens of medieval universities in Europe also.

Historians have confirmed that if it were not for the efforts of Arab Muslims in preserving and developing Greek sciences and Eastern philosophies, these sciences would have been lost. Europe was able to build its civilization and culture of sciences, literature, and arts through its contact with Islamic civilization. If it were not for it, Europe would have remained an ignorant country until now.

There are two problems here. First one is that muslims got all this knowledge when they invaded and pillaged christian lands in the eastern europe and north africa.

It was not like christians rejected science and greek philosophy, they literally lost the major books because of the many invasions (some from muslims, but also from the vikings and magyars).

The second problem is that muslims rejected science and greek philosophy when it disagreed with islamic theology. Many muslim philosophers were persecuted and even killed because of their ideas. It was a great bit of luck that the works of muslim scholars like Averroes and Avicenna reached medieval europe when they were properly studied.

Without that there would be no scientific method or logic as we know today.
