He was a poor orphan and grew up a pagan before finding God. People were angered by his message about God's goodness, and the responsibility that human beings had to respond to that goodness and that mercy by taking care of the poor, and the weak and the sick, the orphan, the widow and by redistributing one's wealth. He was pushed out of his home land saying 'Everything that you see behind me is useless, it's worthless, it's just wood and stone, it means nothing',
He had been preaching for about a decade or so, and during that decade had managed to amass some 70 followers, which is kind of pathetic, if you think about it. So he had a very small group of followers, and he took them with him to create a new kind of society.
This was an era in which the only kind of societal structure that was understood outside of kinship was in a tribe, and the only way you could be a part of a tribe was to be born into a tribe. What he tries to do is recreate society from the ground up. His tribe is one that you don't have to be born into, you can just simply join by following a religion and it's moral teachings. And so therefore it could expand without limit. It didn't matter what ethnicity you were, your kinship wasn't important, your connection or tribal affiliation meant nothing.
His society was not only one in which ethnicity and kinship no longer mattered, it was not only one in which all members of society had an equal access to that society whether you were an orphan or whether you were wealthy, and most importantly, it was a society in which women were for the first time given rights and privileges which they had never conceived of before, the right to own their own properties, the right to inherit property from their husbands and their fathers. Before this time, women could not only not inherit property, they were themselves considered property, and so they would be inherited by their own sons or by other male members of their family. And also most importantly, the right to divorce their husbands, which was something that women never had.
He returns to his home town to the ancient pagan sanctuary, this pantheon really of all the multiple gods of the region, and to cleanse it. He removes all of these idols, he destroys them in front of everyone, and he sanctifies, he re-dedicates it to God. He rededicates it to his new religion of Abraham.
He is Mohammed the founder of Islam. I've have often heard it said that Muslims and Xns have few things in common apart from the heritage of Abraham. Looks to me that we might have plenty to talk about. The above are all quotes taken from the interview with Reza Aslan on Radio Nationals' The Ark.
