Why did the islamic empire choose not to invade western europe after its defeat by france

The Battle of Tours (10 October 732)[8] – also called the Battle of Poitiers and, by Arab sources, the Battle of the Highway of the Martyrs (Arabic: معركة بلاط الشهداء‎, translit. Ma'arakat Balāṭ ash-Shuhadā’)[9] – was fought by Frankish and Burgundian[10][11] forces under Charles Martel against an army of the Umayyad Caliphate led by Abdul Rahman Al Ghafiqi, Governor-General of al-Andalus. It was fought in an area between the cities of Poitiers and Tours, in the Aquitaine of west-central France, near the village of Moussais-la-Bataille, about 20 kilometres (12 mi) northeast of Poitiers. The location of the battle was close to the border between the Frankish realm and the then-independent Duchy of Aquitaine under Odo the Great. The Franks were victorious. Abdul Rahman Al Ghafiqi was killed, and Charles subsequently extended his authority in the south. Details of the battle, including its exact location and the number of combatants, cannot be determined from accounts that have survived. Notably, the Frankish troops won the battle without cavalry.[12]

the crusades are one of the most significant events in the history of europe and the middle east.   they were a series of religious wars carried out by christian crusaders from europe during the timeframe of the middle ages.   beginning in 1095 ce, the crusades saw european knights and noblemen travel to the middle east in an attempt to capture the holy land away from muslim people that had controlled the region for the previous centuries.   the term crusade means ‘cross’.   therefore, the europeans that became crusaders viewed themselves as ‘taking up the cross’.   in fact, many of the crusaders wore crosses on their clothing and armor as they made their pilgrimage to the holy land.

explanation:

i think it was because of how protected egyptian civilization was was which allowed them to evolve without much outside influence.
