Mehrunissa
Mehrunissa is a Persian‑Arabic compound used historically by Muslim families; its elements derive from Persian and Arabic and it has been borne by Muslim women, so it is acceptable in Muslim naming practice.
The well‑documented bearer is the Mughal noblewoman Mehr‑un‑Nisa, who after marriage and rise at court became known by the imperial title Nur Jahan; this is attested in Mughal chronicles.
In New Persian مهر (Mehr) denotes 'sun', 'affection' or 'love' and appears in many Persian names and epithets.
Yes, historically it was used across Persianate societies including Iran, South Asia and parts of the Ottoman world, though it is uncommon today.
There are masculine Persian names beginning with Mehr (e.g., Mehrdad historically), but Mehrunissa itself is specifically feminine because of the element 'Nisa' (women).
