As you noted, Muhammad's father's name was Abdullah (slave of gof), but he died before Muhammad was born. The Quraysh were also known as Ahl Allah (house of god, because they protected the Kaaba) long before Muhammad was born. This presents a problem, since Muhammad was supposed to be the one to introduce the Quraysh to Allah. If you read through the history, the Arabs were moving away from polytheism, with each tribe having their own chief god, which they referred to as Allah. For the Quraysh, it was Hubal. Around the same time, what Josephus said about the Arabs being descendants of Ishmael had finally reached them. He was in the right place at the right time for a psychopath to unite the Arabs by destroying all of the pagan gods, including Hubal, since he picked up different stories about the Abrahamic religions while doing his caravan runs for Khadija. When she died, things really kicked off.
