git push rejected: error: failed to push some refs
git push -f if you have permission, but that will screw up anyone else who pulls from that repo, so be careful.
If that is denied, and you have access to the server, as canzar says below, you can allow this on the server with
git config receive.denyNonFastForwards false
If you are the only the person working on the project, what you can do is:
git checkout master
git push origin +HEAD
This will set the tip of origin/master to the same commit as master (and so delete the commits between 41651df and origin/master)
