Princess_123 - If you want to absolutely guarantee the application won't be approved then the only two real options available to you are to either not submit the application - or to send a letter afterwards canceling / withdrawing your sponsorship. If you cancel or withdraw, CIC will send a letter reflecting this - they won't say the application was refused.
Otherwise, no matter how badly you put together the application, there is always some small chance it will be approved. We have certainly seen applications approved here with minimal evidence - especially in cases where there is a tradition of arranged marriages and little to no prior contact between the husband and wife. Nikkah only weddings are sometimes approved.
So if you submit the application and don't cancel/withdraw - you are taking the chance it will be approved.
