Gausia
No. Gausia is derived from the honorific term Ghawth used in Sufi literature; it is not mentioned as a proper name in the Qur'an.
It evokes the concept of 'ghawth' — succor or spiritual aid — and as a feminine form it signals devotion or association with a Sufi lineage.
It is rare but found mainly in South Asian Muslim communities and among families with Sufi affiliations.
Multiple Latin spellings exist (Gausia, Gawsia, Gawsiya); Arabic script غوثية is the accurate form for the derived adjective.
No. Using the name is an honorific or devotional reference and does not confer or claim sainthood upon the bearer.
