Copy files from one directory to another

Hi

when copy the files from one directory to another as like below,it is tried to copy .[Cc][Ss][Vv] as a file.
cp /home/rha/.[Dd][Aa][Tt]

My objective is to copy all the files (don't care about case sensitive),
Thanks in advance for your valuable reply.

find /home/rha -iname "*.dat" -exec cp {} /destination/dir \;
