Alaikumassalam wa rahmatullah,
For the pronunciation of Inayah, which can also be written as Inaya please see: Inaya.
We do not know any person in history with this name. Inayah Noor will not create a new meaning, but if Inayah al-Noor means “the protection given by light”, and since al-Noor is one of the names of Allah SWT, it would mean “God’s care and protection”. Inaya al-Noor can also be written as Inayatun Nur, Inayat Un Noor or Inayatul Noor.
