He had no religious ties to Joseph.

that's wrong. Mohammed took elements of the Jewish faith (there was a large community of Jews in Mecca and in Medina, why in Medina, the Jews were the ones who sheltered Mohammed when the Meccan pagan Arabs through him out ), from a Christian heresy (Arianism) and from pre-islamic arab paganism (that's the "Satanic verses" where Mo tells Muslims to pay respects to Ul-izzat, Amaat and Izzat, the three daughters of God, who were pre=Islamic goddesses who had idols kept in what is now the Ka'aba (the big black tent in Mecca).

You could say he had no "familial" ties to Joseph, but even that would be probably wrong. As I said, Joseph would, at the very least be his great, great... uncle (through Ishmael), but, more likely, in the 2600 years between Joe and Moe, and considering that there were Jews in Mecca, there MUST have been intermingling of bloodlines.

"You could say he had no "familial" ties to Joseph, but even that would be probably wrong. "

Maybe Mo' slept at a HolyDay Inn Jr and thought he was related to Joseph. BTW, speaking of David the redhead, did you know Mo' also dyed his head red? In some cultures there was an association of red hair with spirituality. Some believe there was a recessive gene in the Levi and Judah tribes where a preponderance of those tribes had ruddy appearances, leading some later speculations that Christ Himself was a redhead.

It is consistent that a counterfeit religion like Islam would have a religious founder, who would even dye his head red in an attempt to bring himself closer to spirituality, instead of humbling himself before God, so that God would be free to grace him with that gift.

The very same Modus Operandi as exhibited by the builders of the Tower of Babel, who sought to elevate man to God, rather than accept the provision of God to man.
