Performing Sunnah of Fajr or Tahiyyat-ul-Masjid

A: If this is the case, perform the Sunnah of Fajr and it will be sufficient for Tahiyyat-ul-Masjid even if there is enough time for both. In case the Iqamah (call to start the Prayer) of Fajr is pronounced before you finish the Sunnah of Fajr, it is better to stop the Sunnah and join the congregational Salah of Fajr after which you should offer the Sunnah or you may offer it after the sunrise.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
