"Correction: January 3, 2016
Because of an editing error, an earlier version of this article misstated the relationship between the Prophet Muhammad and Ali, one of his successors. Ali was the prophet’s cousin and son-in-law, not grandson." So the person educating the readers did not know the relationship between Mohammad and Ali. Also, notice that he had to say "Alawite Shi`its sect" in order to fit into his framework of political analysis.
