Considered by Muslims to be the last of the prophets and the most important messenger of God, Muhammad united the Arab peoples under the banner of Islam. In this nascent community, built from a heterogeneous amalgam of tribes and lineages, the alliances that Muhammad would establish through his marriages would lay the foundations of Islamic politics and law. But, on the other hand, the growing community of Muslims would also draw on the example of the prophet in their daily lives, whose actions were considered to be marked by the divine imprint. Muhammad's behavior towards women was and still is a model for believers to follow. In Esposas y concubinas del Profeta (Wives and Concubines of the Prophet), Arabist and historian Felipe Maíllo Salgado reveals who Muhammad's wives, concubines and suitors were, as well as his legacy in the subsequent expansion and evolution of Islam.
