From Wikipedia:
According to the widely circulated narrative, the school linked with al-Qarawiyyin ultimately became the focal point of the present-day University of al-Qarawiyyin. The assertion that the university was founded by Fatima al-Fihri alongside the mosque is not clearly rooted in historical evidence.[22] The university library, linked to Fatima's story, was restored and reopened in 2016, gaining attention from influential sources such as The Guardian, Smithsonian, TED, and Quartz that claimed that the library was the world's oldest continuously operating library, and that it was founded by Fatima herself. According to Ian D. Morris, a historian of early Islamic societies, there is no empirical evidence to support claims that Fatima founded the library.[23] The lack of historical sources and consultation with historians by commentators, including think-tanks, NGOs, social scientists, journalists, and bloggers, has resulted in numerous "sourceless, baseless" iterations of the Fatima story. As the story is useful to present-day discourses about women and sciences in Islamic history, Morris concludes that the speculation repeated by modern writers "says more about the current value of Fatima as a political symbol than about the historical person herself."
Idk if it's true or not but it checks all of the boxes for misinformation spread in liberal circles.
