I have faith and believe in Allah, and the Quran.
This is enough for me to have faith and believe that the Quran is the word of Allah.
If you told me something I did not know, it might be a revelation to me,but it will not be a revelation from the Almighty.
About calling the Quran Hearsay, it is what you believe, and I do not believe it to be hearsay, so it makes little difference to my faith whether you believe or not.
I do not need to have the whole world confirming the book I believe in,nor do I need the whole world accepting all the Prophets and Messengers (peace be upon them all) in order for me to have firm belief in my religion and its teachings.
I do not need validation from the human race to have faith in Allah.
And for that matter why should I take your alleged word for the Quran not being a revelation. As you can only assume it is not the word of the Almighty as per your belief.
What if you are wrong in your assumptions?
------------------------------
Some who do not believe, call Muhammad (pbuh) a mad man who had hallucinations and some also call him a genius for planning and succeeding in his plan to rule the people of Mecca.
I do not think that a man could be a genius and a hallucinating mad man, it is contradictory in itself.
The Quran mentions the orbit of planets,the forming of a foetus in the womb and its stages.If as some non-believers assume Muhammad(pbuh) to be hallucinating, how can he have come up with such facts?
If he(pbuh) was after power and glory among his people why did he not live a rich life after becoming a leader for his people.There would be days his family would have little to eat, other days he would fast.
So if someone was a mad-man, one would not or could not lead a warring tribalistic people to put down their swords and bow down to the Almighty.Nor would such a person be able to rule justly,nor would such a person be freeing slaves and giving women respect(in a society where female infanticide was the norm).
In all of this and more I cannot find any reason to doubt in the revelation of the Quran by Allah to Muhammad(pbuh) through Gabriel (alaihi salaam)
