I would like to know the usage of Inni Ka Lillah. What is it actually?
Another phrase which confuses me is Inni Qalillah
Is the term controversial, meaning I'm your god?
Inni ka Lillah does not make sense. It literally mean "I am like for Allah" which is nonsense.
You probably mean innaka lillah. Which means, "you belong to Allah", or "you have been created for (the worship of) Allah."
