This whole drama sent a shock wave through Arabia. The trial and execution of the Banu Qurayza announced the grim resolution of the Muslims of Medina. In strictly military terms the Battle of the Moat was a stalemate, but the Quraysh had mustered a force of ten thousand with such fanfare that failing to win was as bad as losing, and this loss helped to stoke a growing myth of Muslim invincibility, communicating a broad impression that this community was not just another powerful tribe feeling its oats but something strange and new. The Muslims lived a distinctly different way of life, they practiced their own devotional rituals, and they had a leader who, when problems came up, went into a trance and channeled advice, he said, from a supernatural helper so powerful that Muslims had no fear of going into battle outnumbered three to one. Who was this helper? At first, many of the unconverted might have thought, It's a really powerful god. But gradually the Muslim message sank in: not a god but the God, the only one. And what if Mohammed was exactly what he claimed to be-the one human being on earth directly connected to the creator of the entire universe? Recruiting people to kill the man grew ever more difficult. Recruiting warriors to go up against his forces grew difficult too. After the Battle of the Moat, the trickle of conversions to Islam became a flood. It's easy to suppose people were converting out of canny self-interest, a desire to join the winning side. Muslims, however, believe there was more to it. In Mohammed's presence, they believe, people were having a religious experience.
