The battle was fought between a raiding Norman force and a larger Muslim army consisting of both Kalbid Sicilians and Zirid Africans.
However after this Robert went home to deal with rebellions and Ibn al-Timnah died, leaving Roger with only a small force and very little opportunity to further expand.
The victory gave Roger free rein to raid wherever he wanted to in Sicily, and additionally caused discontent within the Zirid-Kalbid alliance which ended with the Zirid Prince Ayyub killing Ibn al-Hawas.
Thus when Roger was on one of his raiding expeditions he was met by a Muslim army only a few miles outside Palermo next to the town of Manzil-al-Emir (corrupted by the Christians into Misilmeri).
When Robert Guiscard returned with reinforcements to Sicily in 1072, finally allowing the conquest to continue, the Normans would only find Muslim resistance in the form of sieges, and never again on the open battlefield
