The results show that religious moderation in traditional Muslim families is realized through a balance between adherence to religious teachings and respect for local customs. The values of tolerance, deliberation, and moderation in religion are instilled through role models and dialogue within the family. The Nvivo 12 analysis demonstrates the strong interaction of religious law, customs, and social norms in family religious practices.
