ANSWER:

Can someone make ruqya and make duaa for a child without getting married?

Can someone learn how to swim by making duaa without practicing or learning? 

I am fat and my fatness results in me losing breath quicker than other people who are same fatness as me. Its not life threatening. Online it says vegetables and going to gym can help this. Can i just make ruqyah and dua for Allah to grant me same status as any other fat person who wont lose breath as easily and continue my diet the same which has meat/pizza or must i stop eating that and workout?
