Isra' and Mi'raj
The Isra and Mi'raj are two parts of a story that Muslims tell about Muhammad.  They say that in the year 621, while he was resting in the Kaaba in Mecca, an angel came to him, with an animal called a Buraq.  The Buraq carried Muhammad to a mosque that was far away, and then the Buraq took Muhammad up into heaven.  While in Heaven, Muhammad met Adam and Moses and Allah (God), and then came back down to Earth.
