Samuel ibn Naghrillah in the context of "Maghrebi Jews"

The Alhambra (/ælˈhæmbrə/, Spanish: [aˈlambɾa]; Arabic: الْحَمْرَاء, romanized: al-ḥamrāʼ ) is a palace and fortress complex located in Granada, Spain. It is one of the most famous monuments of Islamic architecture and one of the best-preserved palaces of the historic Islamic world. Additionally, the palace contains notable examples of Spanish Renaissance architecture.

The complex was begun in 1238 by Muhammad I Ibn al-Ahmar, the first Nasrid emir and founder of the Emirate of Granada, the last Muslim state of al-Andalus. It was built on the Sabika hill, an outcrop of the Sierra Nevada which had been the site of earlier fortresses and of the 11th-century palace of Samuel ibn Naghrillah. Later Nasrid rulers continuously modified the site. The most significant construction campaigns, which gave the royal palaces much of their defining character, took place in the 14th century during the reigns of Yusuf I and Muhammad V. After the conclusion of the Christian Reconquista in 1492, the site became the Royal Court of Ferdinand and Isabella (where Christopher Columbus received royal endorsement for his expedition), and the palaces were partially altered. In 1526, Charles V commissioned a new Renaissance-style palace in direct juxtaposition with the Nasrid palaces, but it was left uncompleted in the early 17th century. The Alhambra fell into disrepair over the following centuries, with its buildings occupied by squatters. The troops of Napoleon destroyed parts of it in 1812. After this, the Alhambra became an attraction for British, American, and other European Romantic travellers. The most influential of them was Washington Irving, whose Tales of the Alhambra (1832) brought international attention to the site. The Alhambra was one of the first Islamic monuments to become the object of modern scientific study and has been the subject of numerous restorations since the 19th century. It is now one of Spain's major tourist attractions and a UNESCO World Heritage Site.

Religious ties between Muslims and the Jewish people have existed since the founding of Islam in the Arabian Peninsula in the 7th century; Muhammad's views on Jews were shaped by his extensive contact with the Jewish tribes of Arabia during his lifetime. Islam shares similar values, guidelines, and principles with the Jewish religion, and also incorporates Jewish history as a part of its own. Muslims regard the Israelites, to whom Jews and Samaritans trace their ethnic ancestry, as an important religious concept; they are referenced around 43 times in the Quran, excluding individual prophets, and in many accounts of hadith. Similarly, Moses, the most important Jewish prophet, is also regarded by Muslims as an Islamic prophet and messenger (see: Moses in Islam); his name is mentioned in the Quran 136 times—more than any other individual—and his life is narrated and recounted more than that of any other prophet. The Torah, which is the compilation of the first five books of the Hebrew Bible, is also held by Muslims as an Islamic holy book that was revealed by God (or Allah) through various Israelite prophets and messengers (see: Torah in Islam). Later rabbinic authorities and Jewish scholars, such as Maimonides, engaged in discussions concerning the relationship between Islam and Jewish religious law. Maimonides himself, it has been argued, was influenced by Islamic legal thought while living in the caliphates of his time.

Although the origins of Judaism go back to the time of the ancient Hebrews, it is considered to have started becoming a distinct religion in its own right in the Kingdom of Judah, where it developed as a strictly monotheistic outgrowth of Yahwism. Thus, with a difference of at least 2,000 years, Judaism and Islam share a common geographical origin in what is known today as the Middle East, with the former from the Southern Levant and the latter from the Hejaz. Additionally, both religions claim Abraham as their spiritual patriarch and are thereby classified as Abrahamic religions. Islam was strongly influenced by Judaism in its fundamental religious outlook, structure, jurisprudence, and practice. Because of this similarity, as well as through the influence of Islamic culture and philosophy on the Jewish populations in the Muslim world, there has been considerable and continued physical, theological, and political overlap between the two religions since Islam's founding. Notably, the first Islamic Waqf was donated by a Jew named Mukhayriq, who was a rabbi in the city of Medina. In 1027, the Jewish polymath Samuel ibn Naghrillah became top advisor and military general of the Taifa of Granada in the Muslim-controlled Iberian Peninsula.
