If you are merely asking me of the story-line of the myth, this can readily be found almost anywhere Islam is studied. In short, Mohammed rode his celestial steed from Mecca to Jerusalem during the night. The supernatural horse, named Al Buraq, then rested against what is now the Jewish Wailing Wall before stepping atop the rock now within the Dome of the Rock and then carrying Mohammed off into the heavens. (I would imagine the moon, since Allah was the God of the moon before Mohammed adopted him). Moslems refer to the Wailing Wall as the Al Buraq Wall, and consider it a Holy Site, although one of their few concessions to the Jews has been to let them worship there. Perhaps this is because celestial steeds are so obviously the result of a creative mind, whereas the Dome is a physical structure that can attain Holiness through its' mere nature as a beautiful mosque.
