Prevent rows being deleted

Hello, could you help with this please?

I have code that copies cells A5:D8 and inserts them below. And also have a code that deletes wanted rows, it asks me which row do I wanna delete etc. BUT some people just dont' understand and sometimes they delete those A5:D8 rows also, and then whole workbook is ruined. Is it possible to protect these cells A5:D8 so that they are still able to be copied but users cannot delete them??

this is the code that deletes rows

The intersect function will check if the row a user want to delete INTERSECT your range A5:D8. If so, it will end the Sub. You can also prompt the user with a message telling not to delete this row. I'll leave this to you.
