They did traveled to Europe and tought them everything they knew
Seeking knowledge is obligatory on each Muslim man and woman. There have been many great Muslim scholars among the Muslims.
Muslims established schools for children in Timbuktu to promote education, preserve Islamic knowledge, and cultivate a culture of learning and scholarship in the region.
While the Greek and Roman sources of knowledge were forgotten (either actively or passively) in Christian Europe, Muslim leaders gathered them in Baghdad and Cordoba and translated them into Arabic. When European states were once again mentally ready for this information, they were able to acquire it effortlessly from the Muslims who had held onto it in the interim.

Knowledge of the ancient Romans was preserved by Charlemagne who commissioned monks around Europe to transcribe and preserve Roman manuscripts. Knowledge of the ancient Greeks was preserved by the Greeks themselves. Knowledge of the Egyptians comes from the hieroglyphs in tombs.
ALGEBRA
Medieval Muslims made significant innovations in various fields, notably in mathematics, medicine, and astronomy. They developed algebra and introduced the concept of zero, which revolutionized mathematics. In medicine, scholars like Avicenna wrote comprehensive medical texts that synthesized Greek and Arabic knowledge, advancing practices in diagnosis and treatment. Additionally, they improved astronomical instruments and created detailed star maps, facilitating navigation and enhancing understanding of celestial phenomena.
Muslims do not have one leader, like a pope. There are many many scholars who are well-respected by most Muslims, though.
Nestorians, Muslims, and Jews made significant contributions to medieval science by preserving, translating, and expanding upon ancient texts. Nestorian scholars were instrumental in translating Greek philosophical and scientific works into Arabic and Syriac, facilitating the transmission of knowledge. Muslim scholars, particularly during the Islamic Golden Age, advanced fields such as mathematics, astronomy, and medicine, laying the groundwork for future scientific inquiry. Jewish scholars contributed to this intellectual landscape by engaging with both Islamic and Christian thought, producing important works in philosophy, mathematics, and natural sciences, thus bridging cultural and religious divides.
