MENELISIK ADAB DALAM IBADAH: DIMENSI SPIRITUAL DAN ETIKA DALAM THAHARAH, SHALAT, ZAKAT, PUASA, DAN HAJI

Worship in Islam is not merely the performance of rituals, but also reflects ethical and spiritual values embodied through etiquette. Without etiquette, worship can lose its inner meaning and fail to bring about spiritual and social transformation. Etiquette is a reflection of a deep understanding of the purpose of worship and a servant's closeness to his Lord. It balances the physical and spiritual dimensions, as well as the formal and substantial aspects of every religious practice. This article aims to examine in depth the role of etiquette in perfecting the performance of the five main acts of worship in Islam, namely thaharah, prayer, zakat, fasting, and hajj. This research uses a qualitative descriptive method based on literature review. Data sources include the Qur'an and Hadith of the Prophet SAW, classical literature such as Riyadhus Shalihin and Ihya Ulumuddin, as well as contemporary references such as Tafsir Al-Azhar and scientific studies published in 2020 and beyond. The findings reveal that etiquette plays a crucial role in all forms of worship: purity reinforces both physical and spiritual cleanliness, prayer cultivates spiritual devotion and discipline, zakat instills social awareness and empathy, fasting trains patience and self-control, while the pilgrimage teaches orderliness, humility, and tolerance within the framework of global Islamic interaction. Adab is not merely etiquette but the essence that gives worship meaning and broad impact. Adab also serves as a tool for self-transformation toward becoming an outstanding Muslim in moral, spiritual, and social aspects in the modern era.
