Eh, Sicily was full of Muslim minorities and they never persecuted the local Christians; still ended up deported by 13th century Catholic rulers.

This era is not an era of tolerance by Christians. (Or at least Catholics).
The only way to make Muslim Iberia survive is to have the Reconquista falls.
again this is very general, if we use the maghreb as the primary example of how islam was practiced we have a religion that is continually led by bigoted fanatics who kill everyone who doesn't follow their version of religion, be it christian, jewish or muslim. We know this is a lie that this insanity was located in one region.
In 1074, Alfonso VI's vassal and friend Al-Mamun, king of the Taifa of Toledo died of poisoning in
Córdoba, and was succeeded by his grandson Al-Qádir, who asked for help from the Leonese monarch to end an uprising against him. Alfonso VI took advantage of this request to besiege Toledo, which finally fell on 25 May 1085. After losing his throne, Al-Qádir was sent by Alfonso VI as king of the
Taifa of Valencia under the protection of
Álvar Fáñez. To facilitate this operation and to recover payment of the
parias owed by the city, which had failed to pay him since the previous year, Alfonso VI besieged Zaragoza in the spring of 1086.
[44] In early March, Valencia accepted the rule of Al-Qádir;
Xàtiva resisted requesting the aid of the rulers of Tortosa and Lérida until he was forced to do so. Their raid of the region failed, and they withdrew under harassment by the troops of Fáñez.

After this important conquest, Alfonso VI was entitled
al-Imbraţūr dhī-l-Millatayn ("Emperor of the Two Religions") and as a gesture to the important Muslim population of the city, he promised them, in addition to respecting their properties, the right to use the main
Mosque for their religious activities.
