I have forgotten the location of the verse of Quran which stated directing to the Christians "what you think ? Which one is more difficult ? Creation of Adam or birth of Isha ? Can you help me ?

?? Can you put forth another attempt at your question because what you have written here is hard to understand?

I'm sure English is not your first language and that is fine, but for those of us who are interested in your question, it's difficult to understand what you are asking (based upon the lack of responses thus far).

Sincerely.

I was wondering why a question about something in the Quran was posted on a forum about Christianity...
