First of all, I know why Allah (SWT) use "He" "We", this topic related to Gender and Royalty.
Now my question is, Why Allah (SWT) use "He" instead of "I"?
See this following verse:
He said, "Do not be afraid, ..." | قَالَلَاتَخَافَآۖ (Q20:46)
Why "He"? He could say like this:
I said, "Do not be afraid, ..."
I found another question like this one. A guy answered that question, but he answered why Allah refer himself "We" "He". That's why I am asking the same question again.
If you know the answer please explain this in detail. I have a explanation of mine. But, I want to what other peoples think about this.
