Do the two supererogatory Rak`ahs

Q 5: Is it permissible to perform the supererogatory two Rak`ahs (unit of prayer) before the Fajr (Dawn) Prayer if the time of the Fajr Prayer has passed? Moreover, if a person comes to the Masjid (mosque) after the second Adhan (call to prayer), should he perform the supererogatory Salah performed before the Fajr Prayer or Tahiyyat-ul-Masjid (two-unit Prayer to salute the mosque)?

A: If a Muslim forgets to perform Fajr Prayer or sleeps until the sun rises, they are allowed to perform two Rak`ahs as supererogatory Salah before offering the Fajr Prayer. If a person enters the Masjid to perform Fajr Prayer and there is no time to offer supererogatory Salah, they can perform two Rak`ahs intending both Tahiyyat-ul-Masjid and the two supererogatory Rak`ahs performed before Fajr Prayer.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
