What exactly are you referring to? Early Christians didn’t have the political power to destroy Greek texts, and Muslims didn’t arrive on the scene until 600 years later, so they could not have saved Greek texts from Christian abuse. And even then, Constantinople was the major and often sole source for many Greek texts, particularly after the collapse precipitated by the Muslim invasions and subsequent wars; many of them spread to the West when Roman scholars began fleeing wear and revitalized interest in Greek language and learning.
The main reason a lot of classical learning fell into disuse in the West was that the Germanic peoples migrating in didn’t care much, and there was a language barrier - most stuff was in Greek, and they only knew Latin, for the most part. With a very few exceptions, nobody was going around actively destroying stuff. Indeed, the Church is the main reason so much was preserved in the West, particularly some later popes that took a keen interest in the preservation of ancient texts. Easily the worst thing the West did was the burning of Constantinople during the Fourth Crusade, because again, the Byzantine Empire, even what remained of it by then, was a real center of learning and probably easily the biggest surviving repository of books on the planet at the time, so undoubtedly we lost some texts then.
This isn’t really a religion vs religion thing - the Christians came into an existence in a society and region already steeped in Greek learning, and slowly assumed political control over the region. The Muslims were in an entirely different situation: they were from an underdeveloped region and came into the Middle East via conquest. They simply didn’t know what they had, and the violence of the conquests was a major setback. In some ways, the region never really recovered - that and the Mongol invasions.
That's simplified history at best. Greek texts were much (much) better preserved in the Byzantine empire, and were lost to the West mostly because people forgot Greek and copies decayed.
This has been debunked many years ago and is only perpetuated by wishful and disingenuous revisionism. Ancient Greek texts were being translated in the heart of France half a century before Arabic texts reached the kingdom. https://www.nytimes.com/2008/04/28/world/europe/28iht-politi...
