This research deals with scientific links between Al-Andalus during Emirate Era (138-316 A. H / 756-928 A. D) and the countries of the Islamic world in Al-Maghreb and the Levant, especially with the beginning of the crystallization and maturity of intellectual and cultural personality in Al-Andalus. The study shows ways and means of communication and cultural impact between Al-Andalus and those countries, and considered the trip to be one of the most important of these ways. It also reviewed the manifestations of the scientific links between Andalusians and Al-Maghreb countries, and the relationship between the school of Cordoba and the schools of Fez and Kairouan. As Hijaz was source of religious sciences; Andalusians went there and transferred Hijazian sciences to their country, therefore; the doctrine of Malik spread in their country. Andalusians were also influenced by the systems of the shamids, their schools, religious, literary sciences and arts. Egypt formed an important station for the transfer of Oriental influences to the Maghreb and then to Andalusia. The study also focused on the scientific links with Iraq, since Baghdad represented a global scientific and cultural value, and the Andalusian scientists transferred to Baghdad many aspects of civilization, especially the sciences of philosophy and logic. This contributed to enriching Islamic civilization in different countries in the two wings of the Islamic world.
