Oman is predominantly Ibāḍī Muslim, with social customs that are less strict than those of neighboring Saudi Arabia. Omanis are known for being respectful, kind, helpful, and generous. They're also known for their hospitality, inviting people to their homes and offering them food, desserts, coffee, fruits, and dates. Oman is known for its ancient aflaj oases irrigation system, terraced orchards, adobe fortresses, mosques, wadis, dhows, meteorites, and Al Said, the world's third-largest yacht.
