Andalusia was one of the greatest periods of Islamic history, indeed it is a beacon in the history of mankind as a whole, because it was a source of knowledge on earth for many centuries, from which Europe learned all its lessons of civilization and civility. Its conquest, beyond a doubt, was one of the greatest incidents of the first Hijri century (92 AH/711 CE). That period was the greatest and most prosperous in the history of Andalusia from the beginning of history and perhaps until the end of time.
