Colloquially, a similar term of endearment that is quite common is: نور عینی nuur 3ayni Lit: the light of my eye(s)

I think that the nearest approximation could be نورى نور حياتى not a word to word translation though.

نور حياتي Means light of my life نور = light حياتي = my life

شروق شمسي It's exact translation & really wierd in Arabic I think نور حياتي Said by Mohamed is right in Arabic

my answer is صباحي المشرقة
