Asceticism

Prophet Yahya (John the Baptist), son of Zakariya, was granted wisdom as a child, confirmed the Word of God (Jesus), and was martyred for speaking truth to a corrupt ruler — embodying ascetic devotion, moral courage, and prophetic integrity.

Rabia al-Adawiyya (717-801 CE) was one of the most influential Sufi mystics in Islamic history, renowned for her teachings on divine love and rejection of worship motivated by fear or reward.
