A Rabbi Searches for a Congregation in Saudi Arabia, Birthplace of Islam

RIYADH, Saudi Arabia—In his flat-brimmed hat and long black coat, Jacob Herzog turned a few heads during his first trip to Saudi Arabia last month.

Locals stopped him for photographs as he strolled or shopped for traditional Arabian robes. At a trendy cafe, where the young Saudi hostess surprised him with a greeting of “Shalom,” he sipped from tiny cups of cardamom-scented coffee and ate sticky dates—a kosher option available in the country.
