This work is the result of studies led by me during my long stay in Blanca (Murcia, Spain). The darkness and oblivion opposed my purpose, of a nation that almost for eight centuries dominated in Spain and where the political history of the Spanish Arabs (Muslims) in Murcia remained in the deepest darkness until recently. I do not deny the glory of Dozy and the immense service he has done with its publications to Spain, but we cannot ignore that today we have Arabists in Muria and Spain who follow the footsteps of the wise Dutch and have improved on him a lot. Murcia belonged to Al-Andalus and throughout the period of Islamic rule, Al-Andalus was a remarkable example and outstanding model of tolerance. All Jews and Christians were allowed to maintain their beliefs and live their lives as they desired as long as they respected their Muslim rulers. The Muslims played a principal role in the history of Spain. Their presence illuminated the Iberian Peninsula while the rest of Europe was engulfed in darkness.
