A Brother disagrees with your appraisal of the fate that the Muslims of Spain had suffered.

Answer

The Brother spoke bunkum. He lacks in Deeni knowledge and understanding. The fate which had overtaken the Arab Muslim rule of Spain, and the total expulsion of Muslims and the eradication of Islam by the roots from Spain are the consequences of the worst transgressions of the Muslim population of Spain.

Allah Ta'ala had granted them the wonderful Ni'maat (Bounties) of political power, wealth and great worldly prosperity in general. Instead of expressing gratitude for Allah's bounties by means of increased obedience, they offered 'thanks' by excreting in the very plates they ate. They displayed gross and callous ingratitude with fisq, fujoor, bid'ah and kufr. Their palace ulama halaalized the statues of the royal family which were mounted in the public. They legalized this worst aspect of idolatry. They had degenerated into the dregs of immorality and villainy.

The Brother is in denial of the Qur'aan in which Allah Azza Wa Jal says:

"That (Punishment) is because of what their hands had sent forth. Verily, Allah does not oppress (His) servants.

It (the disobedient lifestyle) was like the ways of the people of

Fir'oun and those before them.

They committed kufr with the Aayaat of Allah. Then Allah apprehended them on account of their sins. Verily, Allah, is Most powerful and stern.

That (Punishment) is because, verily, Allah does not change a Bounty which He has bestowed to a people until they

(themselves)

change what is within themselves (that is, their beliefs, attitudes and deeds).

Like the ways of the people of

Fir'oun and those before them.

They belied the Aayaat of their Rabb, therefore We destroyed Them on account of their sins, and We drowned the people of Fir'oun. They all were zaalimeen.

Verily, the worst of creatures by Allah are the kuffaar. Thus, they do not believe."

(Al-Anfaal, Aayaat 52 – 55)

Again, Allah Ta'ala says:

"Verily, Allah will not change that (Bounty) which is with a people until they (themselves)

change what is within themselves.

And, when Allah decrees a punishment, then there is nothing to thwart it."

(Ar-Ra'd, Aayat 11)

The power, pomp and prosperity enjoyed by the Muslims during their reign of Spain, were undoubtedly the Favours of Allah Ta'ala. No one can deny that all these Ni'maat were snatched away. Who snatched away the Bounties which Allah Ta'ala had bestowed to the Muslims of Spain?

No one other than Allah Azza Wa Jal. The reason for snatching away His Bounties is stated with utmost clarity in the aforementioned Qur'aanic verses and in numerous Ahaadith. Only stupid brothers are in denial of what Allah Ta'ala Himself says.
