No, this was the eighth century, and they were fulfilling Allah's commands (Qur'an 9:5, 9:14, 9:29, Bukhari 1.2.24, et al).
From Medieval Sourcebook:
The Battle of Poitiers [Tours], 732Of course it matters more to the West than to Islam. If Martel and his forces had lost, the Religion of Slaughter would have conquered the continent. For the Mohammedans, this was just one of many fronts in Allah's War Against Humanity.
From 711 Muslim forces crossed the Straits of Gibraltar, conquered the Visigothic Kingdom, and in less than a decade crossed the Pyrenees. In 732, under the command of Abd-er- rahman, they were decisively defeated by Charles Martel and the Franks at the Battle of Poitiers [or Tours]. This event looms much larger in Western history than Muslim - leading to a famous passage of purple prose by Edward Gibbon about minarets rather than spires in Oxford if the Muslims had won. The event was notice [sic] the Muslim world, however, and the following is from an Arab chronicle.
So many Infidels to slay, so little time!
The Moslems smote their enemies, and passed the river Garonne, and laid waste the country, and took captives without number. And that army went through all places like a desolating storm. Prosperity made those warriors insatiable. At the passage of the river, Abderrahman overthrew the count, and the count retired into his stronghold, but the Moslems fought against it, and entered it by force, and slew the count; for everything gave way to their scimitars, which were the robbers of lives.Excessively murderous? Excessively rapacious?
All the nations of the Franks trembled at that terrible army, and they betook them to their king Caldus [Charles Martel], and told him of the havoc made by the Moslem horsemen, and bow they rode at their will through all the land of Narbonne, Toulouse, and Bordeaux, and they told the king of the death of their count. Then the king bade them be of good cheer, and offered to aid them. . . . He mounted his horse, and he took with him a host that could not be numbered, and went against the Moslems.
And he came upon them at the great city of Tours. And Abderrahman and other prudent cavaliers saw the disorder of the Moslem troops, who were loaded with spoil; but they did not venture to displease the soldiers by ordering them to abandon everything except their arms and war-horses. And Abderrahman trusted in the valour of his soldiers, and in the good fortune which had ever attended him. But such defect of discipline always is fatal to armies. So Abderrabman and his host attacked Tours to gain still more spoil, and they fought against it so fiercely that they stormed the city almost before the eyes of the army that came to save it; and the fury and the cruelty of the Moslems towards the inhabitants of the city were like the fury and cruelty of raging tigers. It was manifest that God's chastisement was sure to follow such excesses; and fortune thereupon turned her back upon the Moslems.
Near the river Owar [Loire], the two great hosts of the two languages and the two creeds were set in array against each other. The hearts of Abderrahman, his captains and his men were filled with wrath and pride, and they were the first to begin to fight. The Moslem horsemen dashed fierce and frequent forward against the battalions of the Franks, who resisted manfully, and many fell dead on either side, until the going down of the sun.Where is Charles Martel when you need him?
Night parted the two armies: but in the grey of the morning the Moslems returned to the battle. Their cavaliers had soon hewn their way into the center of the Christian host. But many of the Moslems were fearful for the safety of the spoil which they had stored in their tents, and a false cry arose in their ranks that some of the enemy were plundering the camp; whereupon several squadrons of the Moslem horsemen rode off to protect their tents. But it seemed as if they fled; and all the host was troubled. And while Abderrahman strove to check their tumult, and to lead them back to battle, the warriors of the Franks came around him, and he was pierced through with many spears, so that he died. Then all the host fled before the enemy, and many died in the flight. . . .
