Who conquered Al-Andalus?

Al-Andalus was conquered by Tariq ibn Ziyad with an army of seven thousand fighters, who triumphed over the Goths in a decisive battle in Algeciras. Tariq ibn Ziyad continued to conquer cities, opening Toledo in the year 93 AH. Musa ibn Nusair had sought permission from Caliph Al-Walid ibn Abd al-Malik to invade Al-Andalus, and permission was granted. He then sent Tarif ibn Malik with the first reconnaissance expedition to Al-Andalus in the year 91 AH, and Musa ibn Nusair later participated in the conquest of some cities.
