The Moors invaded Spain in 711. The first crusade was in 1095. A bit of an application of history would help you understand his question.
Sorry, kid, you got it wrong, AGAIN. I mentioned nothing about the invasion of Spain, but if you really wish to discuss it...

As to the initial nature of the expedition, historical opinion takes four directions: (1) that a force was sent to aid one side in a civil war in the hope of plunder and a future alliance; (2) that it was a reconnaissance force sent to test the military strength of the Visigothic kingdom; (3) that it was the first wave of a full–scale invasion; (4) that it was an unusually large raiding expedition with no direct strategic intentions.
(While there are four general opinions, they tend to converge on (1) mentioned above)
Care to try again?
http://en.wikipedia.org/wiki/Battle_of_Guadalete
The Battle of Guadalete was fought in 711 or 712 at an unidentified location between the Christian Visigoths of Hispania under their king, Roderic, and an invading force of Muslim Arabs and Berbers under Ṭāriq ibn Ziyad. The battle was significant as the culmination of a series of Arab-Berber attacks and the beginning of the Islamic conquest of Hispania. In the battle Roderic probably lost his life, along with many members of the Visigothic nobility, opening the way for the capture of Visigothic capital of Toledo.
The battle is sometimes referred to as the Battle of La Janda, Battle of the Río Barbate, or Battle of the Transductine Promontories.
@JR Historians and Hispanists are in general (75% or more) agreement on the political motivation and alliance aspect of this invasion, that Tariq was invited / requested to help in many of the small battles being fought.
