I already documented it in several previous posts, particularly 190. As you are determined to ignore inconvenient facts and records regardless of how many times they are presented to you, posting it again is unlikely to serve any purpose other than to waste my time.
The whole rigamarole began when I pointed out that the Christians fighting to expel Moorish "invaders" from Iberia during Khaldun's lifetime were in fact fighting to expel a Moorish population with 600+ year roots in Iberia. Khaldun sets the period in question. He does not "justify" a claim.
