Al-Ittehad Mosque in Vista, California serves as a mosque and community center for prayer, religious learning, children’s education, and mutual support within the local Muslim community. Its religious life reflects a moderate interpretation of Islam that emphasizes spiritual depth alongside contemporary relevance.
