Fida
While Arabic in origin, Fida has been used in Persian-influenced regions including Bengal, though it is rare in modern Iran.
In Bengali Muslim culture, Fida represents selfless devotion and sacrifice for faith or beloved, often used in Sufi poetry.
The root word appears in the Quran (2:184) regarding fidya (ransom for fasting), though not as a personal name.
Fida is traditionally a masculine name but can be considered unisex in some South Asian contexts.
It is very rare in Persian-speaking Iran but has moderate traditional usage in Bangladesh and parts of India.
