Qudsīyah
Qudsīyah comes from the Arabic root ق د س meaning 'holiness' and literally denotes 'sacred' or 'pertaining to sanctity.'
No. Qudsīyah is not a Quranic proper name; it is a classical Arabic adjective meaning 'sacred' and has been used historically in Muslim societies as a given name.
The name (and variants such as Qudsia/Qudsiyyah) is attested historically in Ottoman and South Asian Muslim naming records and has been used by families wishing to express devotional sentiment.
A common pronunciation rendering is QUD-see-yah (with an initial uvular 'q' and the stress on the second syllable).
Yes. It is an Arabic-derived name with clear religious meaning (sacred/holy) and has historical use among Muslims; it is acceptable as a Muslim girl's name.
