Yes,what you did is perfect.
Only stupids who are always insist to ask for an evidence from the quran that it is true from god,because they will go around such circle like idiots.
Be wise enough not to put yourself in such circle.
again and again and again,that is depend on faith,if you told me that your father's name is so and so,
should i ask for an evidence that your father did it and you are his real son.
So that is the faith,you trust that your father did it,eventhough you did see nothing.
if you have faith,then you will not fetch for an evidence
but if you dont have faith,you will still be in doubt,eventhough you have an evidence
Thank you England my lionheart for that wise circle drawing which make it clear that such discussions are always pointless
