BIND and CNAME-ing

Hi,

I am stuck at this situation:

Where I have a domain:  abc.com :

I would like to have user who type  http://abc.com (without the www)  
redirected to a a different site for example :  www.xyz.com
Redirection for www.abc.com to www.xyz.com works fine.

I have tried CNAME-ing abc.com to www.xyz.com but that wouldn't work  
(I can see it why).
Is there a way to do this in BIND zone configuration?

Thanks
