My family is making duaa for something for 1 year. We made all the kinds of duaa, prayers etc. Including duaa's which they say Allah will never refuse them. We tried EVERYTHING, but it didnt get accepted (we wanted a baby boy, but got a girl). We are still happy with her, but it confuses us why it became a girl, since the duaa we made said that Allah never refuses this Dua. What could be a reason that Allah didnt accept it? Did we too much, sins etc?

We see that the mother of Maryam wanted a boy as well but Allah gave her a daughter who was Maryam.
