If Islam Means Submission, Who Submitted And To Whom?

a quranic revelation approved it; (2) after praying toward Jerusalem failed to win over the Jews, Muhammad wished to turn toward the Kaaba and Allah obliged - hence Mecca to this day; (3) Muslims were capped at four wives but Muhammad got a wildcard for 11, plus sexual slavery approved;

(4) he was given the go-ahead to attack caravans, which the OP calls a root of banditry and terrorism; (5) the daily prayers were reduced from 50 to 5 because Muhammad was uncomfortable; (6) when commanded to read he said he could not, and Allah left him alone.

The OP adds that the shahada requires accepting Muhammad as messenger alongside Allah, conflicting with the claim that Islam had other prophets before him, and concludes: if you submit to Allah you invariably submit to Muhammad - so in Islam, who do Muslims submit to between Muhammad and Allah?
