“Seeking peace of mind, Muhammad often retreated to a cave outside Mecca to pray and reflect. Muslims believe one night, in 610, the angel Gabriel appeared before Muhammad in a cave. Gabriel told him to recite, or say loudly messages from God.” p.254 My world History (Early Ages)
Written as if it were a proven fact, Christian students who know the name Gabriel were influenced into thinking this is the same angel Gabriel of the Bible. But compared to the Gabriel of the Bible, this angel Gabriel of the Quran is far from the angel Gabriel of the New Testament.
