 Throughout his writings he showed deep conviction that Islam was the right faith and that it would triumph again in Spain within his lifetime.He wrote at least three extant works, the "Brief compendium of our sacred law and sunna" (c. 1533), the "Tafsira" (c. 1533), and the "Summary of the Account and Spiritual Exercise" (c. shortly before 1550), all written in Spanish with Arabic script ("aljamiado"), and primarily about religious topics.In addition to the religious content, the works included accounts of his travels, his meetings with other clandestine Muslims, and descriptions of their religious practices and discussions.
