"Islamic" gender neutral names?

Question

I know there are a few names that go for boys and girls like Noor and Eeman. 
I would like to hear more as I can't find very many nice sounding names for my angel baby. We didn't find out the gender and now obviously never will until Jannah in Sha Allah.

Answer

I have two colleagues called Amine - one male and one female. They are from different countries but both Muslims so it might work?

Answer

Perhaps words in old Arabic that are not necessarily in the Quran but are still related to faith? It's such a beautiful language I'm sure there are meaningful names describing almost anything.
Because Arabic is a grammatically gendered language like Spanish and Portuguese, It may be hard to find a true gender-neutral name.
