(Fatwa: 760/641/B=1433)
One may offer the sunnah of Fajr and Zuhr after beginning of the time even before azan but it is not right to offer the two rakah sunnah muakkadah of post-Zuhr before fardh in emergency. If offered it shall be nafl. It shall be necessary to offer two rakah sunnah muakkadah after fardh again.
