The one who gets first position, for him, there is a reward.
Is this a right sentence? I think it has an issue:
Because "The one" is already present so 'him' is additional. What does this refer to? If we write it like this:
There is a reward for him who...
Where will 'the one' go?
And if we write it this way:
There is a reward for the one who...
Where will 'him' go?
