Question: 

Can I make a dual intention for Qurbani: Fard and Sadaqah Qurbani combined in my name for Shifa? 

Answer: 

Yes, a person can make dual intentions for Qurbani when it is a big animal, such as a camel or cow etc. In other words, he could purchase one share in a cow for his Waajib Qurbani and purchase another share in the same cow for his Sadaqah Qurbani.
