"On that light, I would like to request you to go through Quran and verify by yourself if there is anything contradictory in Quran itself"
There are lots of examples and I would think it would behove you find them rather than me tempt you away from your faith. As a hint I would suggest you look at all the scientific 'claims' in the Qu'ran - some are just untrue, most were known and recorded a thousand years before the prophet, some are lucky guesses, but NONE are clear and un-ambiguious.
The rules are clearly a doctrine to rule a people and keep power in the hands of men.
And the 'human hand' comment was meant as written by man not a deity - for all I know it might be unchanged since the prophet's time, that's not what I meant though.
