Fidwi
While the name itself is not mentioned, the root concept of fida (ransom/sacrifice) appears in verses like 2:207 regarding those who sell themselves seeking God's pleasure.
In Sufism, Fidwi represents the advanced disciple who has achieved self-annihilation (fana) and lives solely as a servant of the Divine Will.
It remains extremely rare, occasionally found in traditional Sufi families in Iran, Afghanistan, and South Asia who maintain classical naming conventions.
Fida is the Arabic term for ransom, while Fidwi is the Persianized form specifically connoting the state of being a devoted sacrifice.
The name suits individuals with deep empathy, service-oriented natures, and spiritual intensity.
