Question

Why did Mohammad leave the Arabian Peninsula?

Answer 1

He didnt

when he died his companions (Mostly Arabs) spread the word of Islam. and soon the Arabic Language Became the most common Language in the Middle East

Answer 2

It was the Prophet Muhammad himself who attempted to negate the positive image of the Jew that had been prevalent earlier.  According to historian Bernard Lewis, the Prophet Muhammad's original plan had been to induce the Jews to adopt Islam; when Muhammad began his rule at Medina in AD 622 he counted few supporters, so he adopted several Jewish practices-including daily prayers facing toward Jerusalem and the fast of Yom Kippur-in the hope of wooing the Jews.  But the Jewish community rejected the Prophet Muhammad's religion, preferring to adhere to its own beliefs, whereupon Muhammad subsequently substituted Mecca for Jerusalem, and dropped many of the Jewish practices.

Jews faced the danger of incurring the wrath of a Muslim, in which case the Muslim could charge, however falsely, that the Jew had cursed Islam, an accusation against which the Jew could not defend himself.  Islamic religious law decreed that, although murder of one Muslim by another Muslim was punishable by death, a Muslim who murdered a non-Muslim was given not the death penalty, but only the obligation to pay "blood money" to the family of the slain infidel.  Even this punishment was unlikely, however, because the law held the testimony of a Jew or a Christian invalid against a Muslim, and the penalty could only be exacted under improbable conditions--when two Muslims were willing to testify against a brother Muslim for the sake of an infidel.  

Edit:  I see that so far I have 6 thumbs down.  The first five are one person, but I can't figure out who gave me the 6th thumb down.  Can anybody clue me in?

Answer 3

I don't believe he ever did.  I believe his followers distorted another story to make it seem more legitimate.

Answer 4

Do you mean physically or in a dream like his Night Journey?

I've been told that, according to some opinions, Mohammed traveled as far as Babylonia. Maybe someone else can  provide links for that. In his youth, he was supposed to have travelled along trade routes in the region, albeit mostly in Arabia.
