With regards to your statement, on top of the above link,
I have heard zakir naik say somethin along the lines of:
This is nto a contradiction but a contradistinction, meaning that this talks about different things used to make man.
For example, if I say I made a cup of tea out of water, and then I later went to say I made a cup of tea out of tea leaf, would it be contradictory? Nope its not a contradiction but a contradisticntion.
Sounded cool

but anyhow, read more on it akhi.
