What are the motifs in Muhammad: A Biography of the Prophet by Karen Armstrong?

Decent behavior is a recurring idea. Muhammad was always concerned with the behavior of the tribe members in Mecca. This is why he began his preachings and tried to correct the deficiencies that he saw in the behavior of his fellow Meccans. The decent behavior that he preached concerned the treatment of others, especially women and the disadvantaged members of society. Muhammad felt these two groups had a right to humane treatment. He did much to advance the status of women in seventh century Arab society.
