Razib Khan: was the Prophet Muhammad a Jew?Muhammad's sons didn't survive but he had lots of cousins, who descend from Qusay bin Kilab. Their Y-chromosome is labeled L859+. This is closely related to Y-chromosome ZS22012 which is Jewish, more distantly related to other lineages like the Cohen gene.
Always thought there was something about the name "Quraysh". Like "little Koresh", Koresh being a (famously) messianic title in second-temple Judaism and, er, Waco.
